Small glutamate-containing peptides bearing coumarin derivatives as fluorescent leaving groups attached to the γ-carboxylic acid group of the Glu residue were synthesised and investigated with regard to their potential to act as substrates for transglutam
MODIFICATION OF ENZYMATIC CROSSLINKERS FOR CONTROLLING PROPERTIES OF CROSSLINKED MATRICES
-
, (2012/11/07)
Improved matrix or hydrogel that is formed by enzymatic crosslinking of polymers wherein the crosslinking enzyme molecules have been modified for the purpose of improving the crosslinking density, mechanical properties, or other properties of the matrix, and/or to provide improved control over the rate and/or extent of crosslinking, wherein the enzyme molecules are modified to alter the perceived volume of the enzyme molecules in the crosslinked matrix being formed. Methods of production and of use are also provided.

Transglutaminases (EC 2.3.2.13) (TGases) catalyze calcium-dependent acyl transfer reactions between peptide-bound glutamine residues as acyl donors and peptide-bound lysine residues as acyl acceptors, resulting in the formation of intermolecular ε-(γ-glutamyl)lysine crosslinks. The mechanistic details of its "ping-pong" transamidation reaction remain unknown. In particular, few studies have been published probing the nucleophilicity of TGase using acyl-donor substrates of varied electrophilicity. Herein we report the synthesis of activated esters of carbonates, carbamates, and thiocarbonates and their reactions with simple thiols, as a nonenzymatic point of reference, and with the catalytic cysteine residue of guinea pig liver TGase. Our kinetic results show that the simple substitution of a side chain methylene unit by oxygen or sulphur had a surprising effect on both substrate affinity and acylation reactivity. Furthermore, they provide unexpected insight into the importance of a side chain heteroatom for conferring affinity for tissue TGase as well as revealing an interesting class of irreversible inhibitors.
V8 PROTEINASE-CATALYZED PEPTIDE SYNTHESIS IN HYDROPHILIC ORGANIC SOLVENTS WITH LOW WATER CONTENT
Cerovsky, Vaclav
, p. 3421 - 3424 (2007/10/02)
Free Staphylococcus aureus V8 proteinase was applied to coupling reactions of Z-Glu-OMe, Z-Glu-OBzl, Z-Ala-Glu-OMe, and Z-Ala-Ala-Glu-OMe with various amino acid amides and peptides in acetonitrile containing 5 vol. percent of water.No synthesis of Z-Asp-Leu-NH2 was achieved under the same conditions.The synthesis of Z-Glu-Leu-NH2 proceeded analogously also in 2-propanol or tert-butanol.
