Abstract
Lectins are (glyco)proteins capable of reversibly binding to specific carbohydrates, thus having various functions and applications. Plant lectins are the best studied, and the Leguminoseae family is highlighted in a number of published works, especially species of the Papilionoideae subfamily. Dalbergieae is one of the tribes in this subfamily comprising 49 genera and over 1300 species. From this tribe, about 26 lectins were studied, among which we can highlight the Arachis hypogaea lectin, widely used in cancer studies. Dalbergieae lectins demonstrate various carbohydrate specificities and biological activities including anti-inflammatory, vasorelaxant, nociceptive, antibacterial, antiviral among others. Structurally, these lectins are quite similar in their three-dimensional folding but present significant differences in oligomerization patterns and in the conservation of carbohydrate-recognition domain. Despite the existence of structural data from some lectins, only sparse literature has reported on this tribe's diversity, not to mention the range of biological effects, determined through specific assays. Therefore, this work will review the most important studies on Dalbergieae lectins and their potential biomedical applications.

Combining site-specific mutagenesis and seeding as a strategy to crystallize 'difficult' proteins: the case of Staphylococcus aureus thioredoxin. Acta Crystallogr Sect F Struct Biol Cryst Commun 2006; 62:1255-8. [PMID: 17142910 PMCID: PMC2225371 DOI: 10.1107/s1744309106047075] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2006] [Accepted: 11/07/2006] [Indexed: 11/10/2022]
Abstract
The P31T mutant of Staphylococcus aureus thioredoxin crystallizes spontaneously in space group P2(1)2(1)2(1), with unit-cell parameters a = 41.7, b = 49.5, c = 55.6 A. The crystals diffract to 2.2 A resolution. Isomorphous crystals of wild-type thioredoxin as well as of other point mutants only grow when seeded with the P31T mutant. These results suggest seeding as a valuable tool complementing surface engineering for proteins that are hard to crystallize.

J Mol Biol 2006; 361:153-67. [PMID: 16824540 DOI: 10.1016/j.jmb.2006.06.006] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2006] [Revised: 05/30/2006] [Accepted: 06/07/2006] [Indexed: 10/24/2022]
Abstract
The interplay between metal binding, carbohydrate binding activity, stability and structure of the lectin from Pterocarpus angolensis was investigated. Removal of the metals leads to a more flexible form of the protein with significantly less conformational stability. Crystal structures of this metal-free form show significant structural rearrangements, although some structural features that allow the binding of sugars are retained. We propose that substitution of an asparagine residue at the start of the C-terminal beta-strand of the legume lectin monomer hinders the trans-isomerization of the cis-peptide bond upon demetallization and constitutes an intramolecular switch governing the isomer state of the non-proline bond and ultimately the lectin phenotype.
