Abstract
The objective of the current review is to summarize the current state of optical methods in redox biology. It consists of two parts, the first is dedicated to genetically encoded fluorescent indicators and the second to Raman spectroscopy. In the first part, we provide a detailed classification of the currently available redox biosensors based on their target analytes. We thoroughly discuss the main architecture types of these proteins, the underlying engineering strategies for their development, the biochemical properties of existing tools and their advantages and disadvantages from a practical point of view. Particular attention is paid to fluorescence lifetime imaging microscopy as a possible readout technique, since it is less prone to certain artifacts than traditional intensiometric measurements. In the second part, the characteristic Raman peaks of the most important redox intermediates are listed, and examples of how this knowledge can be implemented in biological studies are given. This part covers such fields as estimation of the redox states and concentrations of Fe-S clusters, cytochromes, other heme-containing proteins, oxidative derivatives of thiols, lipids, and nucleotides. Finally, we touch on the issue of multiparameter imaging, in which biosensors are combined with other visualization methods for simultaneous assessment of several cellular parameters.

Abstract
Heme, found in hemoproteins, is a valuable source of iron, an essential mineral. The need for an alternative hemoprotein source has emerged due to the inherent risks of large-scale livestock farming and animal proteins. Corynebacterium glutamicum, regarded for Qualified Presumption of Safety or Generally Recognized as Safe, can biosynthesize hemoproteins. C. glutamicum single-cell protein (SCP) can be a valuable alternative hemoprotein for supplying heme iron without adversely affecting blood fat levels. We constructed the chemostat culture system to increase hemoprotein content in C. glutamicum SCP. Through adaptive evolution, hemoprotein levels could be naturally increased to address oxidative stress resulting from enhanced growth rate. In addition, we used several specific plasmids containing growth-accelerating genes and the hemA promoter to expedite the evolutionary process. Following chemostat culture for 15 days, the plasmid in selected descendants was cured. The evolved strains showed improved specific growth rates from 0.59 h-1 to 0.62 h-1, 20% enhanced resistance to oxidative stress, and increased heme concentration from 12.95 µg/g-DCW to 14.22-15.24 µg/g-DCW. Notably, the putative peptidyl-tRNA hydrolase-based evolved strain manifested the most significant increase (30%) of hemoproteins. This is the first report presenting the potential of a growth-acceleration-targeted evolution (GATE) strategy for developing non-GMO industrial strains with increased bio-product productivity.

Abstract
Perfluorooctane sulfonate (PFOS), a representative of perfluorinated compounds in industrial and commercial products, has posed a great threat to animals and humans via environmental exposure and dietary consumption. Herein, we investigated the effects of PFOS binding on the redox state and stability of two hemoproteins (hemoglobin (Hb) and myoglobin (Mb)). Fluorescence spectroscopy, circular dichroism and UV-vis absorption spectroscopy demonstrated that PFOS could induce the conformational changes of proteins along with the exposure of heme cavity and generation of hemichrome, which resulted in the increased release of free hemin. After that, free hemin liberated from hemoproteins led to reactive oxygen species formation, lipid peroxidation, cell membrane damage and loss of cell viability in vascular endothelial cells, while neither Hb nor Mb did show cytotoxicity. Chemical inhibitors of ferroptosis effectively mitigated hemin-caused toxicity, identifying the hemin-dependent ferroptotic cell death mechanisms. These data demonstrated that PFOS posed a potential threat of toxicity through a mechanism which involved its binding to hemoproteins, decreased oxygen transporting capacity, and increased hemin release. Altogether, our findings elucidate the binding mechanisms of PFOS with two hemoproteins, as well as possible risks on vascular endothelial cells, which would have important implications for the human and environmental toxicity of PFOS.

Abstract
Iron is essential for nearly all aerobic organisms. One source of iron in nature is in the form of heme. Due to its critical physiological importance as a cofactor for several enzymes, organisms have evolved various means to secure heme for their needs. In the case of heme prototrophs, these organisms possess a highly conserved eight-step biosynthetic pathway. Another means used by many organisms is to acquire heme from external sources. As opposed to the knowledge of enzymes responsible for heme biosynthesis, the nature of the players and mechanisms involved in the acquisition of exogenous heme is limited. This review focuses on a description of newly discovered proteins that have novel functions in heme assimilation in the model organism Schizosaccharomyces pombe. This tractable model allows the use of the power of genetics to selectively block heme biosynthesis, setting conditions to investigate the mechanisms by which external heme is taken up by the cells. Studies have revealed that S. pombe possesses two independent heme uptake systems that require Shu1 and Str3, respectively. Heme-bound iron is captured by Shu1 at the cell surface, triggering its internalization to the vacuole with the aid of ubiquitinated proteins and the ESCRT machinery. In the case of the plasma membrane transporter Str3, it promotes cellular heme import in cells lacking Shu1. The discovery of these two pathways may contribute to gain novel insights into the mechanisms whereby fungi assimilate heme, which is an essentially biological process for their ability to invade and colonize new niches.

Abstract
Manganese peroxidase (MnP) is a fungal heme-containing enzyme which oxidizes Mn2+ to Mn3+, a diffusible and strong non-specific oxidant capable of attacking bulky phenolic substrates. Therefore, MnP is indispensable in the polymer and paper industries. Previous attempts of MnP expression in Escherichia coli resulted in the formation of inclusion bodies which required in vitro refolding. Aiming to investigate the bacterial production of MnP, we have revealed an interesting mechanism underlying chaperone-assisted maturation of this enzyme to its active form. Since we previously found that in vitro expression of MnP in E. coli system depends on disulfide bond isomerase DsbC, we chose SHuffle T7 Express, an E. coli constitutively expressing DsbC, as the host for in vivo expression of MnP. Initially, only a low amount of the enzyme was present in the soluble fraction, with no detectable peroxidase activity. Co-expression of MnP with different chaperone revealed that DnaK, DnaJ, and GrpE contributed the most to the solubility improvement, however, remained in a complex with the MnP, preventing the enzyme to assume its active conformation. We resolved this by in vitro maturation, involving incubation of the MnP-chaperone complex with hemin, ATP, and ATP regeneration system. While ATP enables the chaperones to finish the refolding cycle and release the MnP in its correctly folded form, hemin supports the formation of the holo-enzyme with fully recovered peroxidase activity. We believe that the findings of this paper will serve as an important clue for establishing the bacterial production of fungal peroxidases in the future.

Abstract
Hemoproteins are commonly found in nature, and involved in many important cellular processes such as oxygen transport, electron transfer, and catalysis. Rational design of hemoproteins can not only inspire novel biocatalysts but will also lead to a better understanding of structure-function relationships in native hemoproteins. Here, the heme nitric oxide/oxygen-binding protein from Caldanaerobacter subterraneus subsp. tengcongensis (TtH-NOX) is used as a novel scaffold for oxidation biocatalyst design. We show that signaling protein TtH-NOX can be reengineered to catalyze H2O2 decomposition and oxidation of 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) by H2O2. In addition, the role of the distal tyrosine (Tyr140) in catalysis is investigated. The mutation of Tyr140 to alanine hinders the catalysis of the oxidation reactions. On the other hand, the mutation of Tyr140 to histidine, which is commonly observed in peroxidases, leads to a significant increase of the catalytic activity. Taken together, these results show that, while the distal histidine plays an important role in hemoprotein reactions with H2O2, it is not always essential for oxidation activity. We show that TtH-NOX protein can be used as an alternative scaffold for the design of novel biocatalysts with desired reactivity or functionality. H-NOX proteins are homologous to the nitric oxide sensor soluble guanylate cyclase. Here, we show that the gas sensor protein TtH-NOX shows limited capacity for catalysis of redox reactions and it can be used as a novel scaffold in biocatalysis design.
