Abstract
Glucosylglycerate (R-2-O-α-D-glucopyranosyl-glycerate, GG) is a negatively charged compatible solution with versatile functions. Here, an artificial in vitro enzymatic cascade was designed to feasibly and sustainably produce GG from affordable starch and glycerol. First, Spirochaeta thermophila glucosylglycerate phosphorylase (GGP) was carefully selected because of its excellent heterologous expression, specific activity, and thermostability. The optimized two-enzyme cascade, consisting of alpha-glucan phosphorylase (αGP) and GGP, achieved a remarkable 81 % conversion rate from maltodextrin and D-glycerate. Scaling up this cascade resulted in a practical concentration of 58 g/L GG with a 62 % conversion rate based on the added D-glycerate. Additionally, the production of GG from inexpensive starch and glycerol in one-pot using artificial four-enzyme cascade was successfully implemented, which integrates alditol oxidase and catalase with αGP and GGP. Collectively, this sustainable enzymatic cascade demonstrates the feasibility of the practical synthesis of GG and has the potential to produce other glycosides using the phosphorylase-and-phosphorylase paradigm.

Turning waste into treasure: Biosynthesis of value-added 2-O-α-glucosyl glycerol and d-allulose from waste cane molasses through an in vitro synthetic biology platform. BIORESOURCE TECHNOLOGY 2024; 391:129982. [PMID: 37926357 DOI: 10.1016/j.biortech.2023.129982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 11/02/2023] [Accepted: 11/02/2023] [Indexed: 11/07/2023]
Abstract
The efficient and economical conversion of agricultural waste into glycosides and rare sugars is challenging. Herein, an in vitro synthetic bienzyme system consisting of sucrose phosphorylase and d-allulose 3-epimerase was constructed to produce 2-O-α-glucosyl glycerol and d-allulose from cane molasses. Lactic acid in the cane molasses significantly induced sucrose phosphorylase to hydrolyze sucrose instead of glycosylation. Notably, lactic acid significantly inhibited the catalytic performance of d-allulose 3-epimerase only in the presence of Na+ and K+, with an inhibition rate of 75%. After removing lactic acid and metal ions, 116 g/L 2-O-α-glucosyl glycerol and 51 g/L d-allulose were synthesized from 500 mM sucrose in the treated cane molasses with a sucrose consumption rate of 97%. Our findings offer an economically efficient and environmentally friendly pathway for the industrial production of glycosides and rare sugars from food industry waste.

Abstract
Cis-3-hydroxypipecolic acid (cis-3-HyPip) is the crucial part of many alkaloids and drugs. However, its bio-based industrial production remains challenging. Here, lysine cyclodeaminase from Streptomyces malaysiensis (SmLCD) and pipecolic acid hydroxylase from Streptomyces sp. L-49973 (StGetF) were screened to achieve the conversion of L-lysine to cis-3-HyPip. Considering the high-cost of cofactors, NAD(P)H oxidase from Lactobacillus sanfranciscensis (LsNox) was further overexpressed in chassis strain Escherichia coli W3110 ΔsucCD (α-ketoglutarate-producing strain) to construct the NAD+ regeneration system, thus realizing the bioconversion of cis-3-HyPip from low-cost substrate L-lysine without NAD+ and α-ketoglutarate addition. To further accelerate the transmission efficiency of cis-3-HyPip biosynthetic pathway, multiple-enzyme expression optimization and transporter dynamic regulation via promoter engineering were conducted. Through fermentation optimization, the final engineered strain HP-13 generated 78.4 g/L cis-3-HyPip with 78.9% conversion in a 5-L fermenter, representing the highest production level achieved so far. These strategies described herein show promising potentials for large-scale production of cis-3-HyPip.
