Abstract
Replacement of disulfide bonds with non-reducible isosteres can be a useful means of increasing the in vivo stability of a protein. We describe the replacement of the A-chain intramolecular disulfide bond of human relaxin-3 (H3 relaxin, INSL7), an insulin-like peptide that has potential applications in the treatment of stress and obesity, with the physiologically stable dicarba bond. Solid phase peptide synthesis was used to prepare an A-chain analogue in which the two cysteine residues that form the intramolecular bond were replaced with allylglycine. On-resin microwave-mediated ring closing metathesis was then employed to generate the dicarba bridge. Subsequent cleavage of the peptide from the solid support, purification of two isomers and their combination with the B-chain via two intermolecular disulfide bonds, then furnished two isomers of dicarba-H3 relaxin. These were characterized by CD spectroscopy, which suggested a structural similarity to the native peptide. Additional analysis by solution NMR spectroscopy also identified the likely cis/trans form of the analogs. Both peptides demonstrated binding affinities that were equivalent to native H3 relaxin on RXFP1 and RXFP3 expressing cells. However, although the cAMP activity of the analogs on RXFP3 expressing cells was similar to the native peptide, the potency on RXFP1 expressing cells was slightly lower. The data confirmed the use of a dicarba bond as a useful isosteric replacement of the disulfide bond.

Abstract
A method to facilitate regioselective formation of multiple dicarba isosteres of cystine is described. A sequence of ruthenium-catalyzed cross metathesis and rhodium-catalyzed hydrogenation of nonproteinaceous allylglycine derivatives has been developed to achieve high-yielding and unambiguous formation of diaminosuberic acid derivatives. Allylglycine derivatives readily undergo ruthenium-catalyzed metathesis and hydrogenation to yield diaminosuberic acid derivatives in near quantitative yield. Under the same experimental conditions, prenylglycine was found to be inert to both Grubbs' and Wilkinson's catalyzed metathesis and hydrogenation, respectively, but was readily activated for metathesis via cross metathesis with Z-butene. Subsequent cross metathesis of the metathesis-formed crotylglycine derivative, followed by hydrogenation, yielded the second diaminosuberic acid derivative in excellent yield.

Abstract
Organic co-solvent-induced secondary conformation of alpha(17-40) of human hemoglobin facilitates the splicing of E30-R31 in a mixture of its complementary segments by V8 protease. The amino acid sequence of alpha(17-40) has been conceptualized by the general structure FR(I)-EALER-FR(II) and the pentapeptide sequence EALER playing a major role in inducing the alpha-helical conformation. The primary structure of alpha(17-40) has been engineered in multiple ways to perturb one, two, or all three regions and the influence of the organic co-solvent-induced conformation and the concomitant resistance of E30-R31 peptide bond to V8 protease digestion has been investigated. The central pentapeptide (EALER), referred to here as splicedon,(3) appears to dictate a primary role in facilitating the splicing reaction. When the same flanking regions are used, (1) splicedons that carry amino acid residues of low alpha-helical potential, for example G at position 2 or 3 of the splicedon, generate a conformational trap of very low thermodynamic stability, giving an equilibrium yield of only 3%-5%; (2) splicedons with amino acid residues of good alpha-helical potential generate a conformational trap of medium thermodynamic stability and give an equilibrium yield of 20%-25%; (3) the splicedons with amino residues of good alpha-helical potential and also an amino acid that can generate an i, i + 4 side-chain carboxylate-guanidino (amino) interaction, a conformational trap of maximum thermodynamic stability is generated, giving an equilibrium yield of 45%-50%; and (4) the thermodynamic stability of the conformational trap of the spliced peptide is also influenced by the amino acid composition of the flanking regions. The V8 protease resistance of the spliced peptide bond is not a direct correlate of the amount of alpha-helical conformation induced into the product. The results of this study reflect the unique role of the splicedon in translating the organic co-solvent-induced product conformation as a site-specific stabilization of the spliced peptide bond. It is speculated that the splicedon with higher alpha-helical potential as compared to either one of the flanking regions achieves this by integrating its potential with that of the flanking region(s). Exchange of flanking regions with the products of other V8 protease-catalyzed splicing reactions will help to establish the general primary structural requirements of this class of splicing reactions and facilitate their application in modular construction of proteins.

Abstract
This article reports on the design and characteristics of substrate mimetics in protease-catalyzed reactions. Firstly, the basis of protease-catalyzed peptide synthesis and the general advantages of substrate mimetics over common acyl donor components are described. The binding behavior of these artificial substrates and the mechanism of catalysis are further discussed on the basis of hydrolysis, acyl transfer, protein-ligand docking, and molecular dynamics studies on the trypsin model. The general validity of the substrate mimetic concept is illustrated by the expansion of this strategy to trypsin-like, glutamic acid-specific, and hydrophobic amino acid-specific proteases. Finally, opportunities for the combination of the substrate mimetic strategy with the chemical solid-phase peptide synthesis and the use of substrate mimetics for non-peptide organic amide synthesis are presented.

Abstract
The concept of substrate mimetic strategy represents a new powerful method in the field of enzymatic peptide synthesis. This strategy takes advantage of the shift in the site-specific amino acid moiety from the acyl residue to the ester-leaving group of the carboxyl component enabling acylation of the enzyme by nonspecific acyl residues. As a result, peptide bond formation occurs independently of the primary specificity of proteases. Moreover, because of the coupling of nonspecific acyl residues, the newly formed peptide bond is not subject to secondary hydrolysis achieving irreversible peptide synthesis. Here, we report the combination of solid-phase peptide synthesis with substrate mimetic-mediated enzymatic peptide fragment condensations. First, the utility of the oxime resin strategy for the synthesis of peptide fragments in the form of substrate mimetics esterified as 4-guanidinophenyl-, phenyl- and mercaptopropionic acid esters was investigated. The study was completed by using the resulting N(alpha)-protected peptide esters as acyl donors in trypsin-, alpha-chymotrypsin- and V8 protease-catalyzed fragment condensations.

Abstract
Papain-catalyzed regioselective cleavage of alpha-methyl ester in Z-DL-Asu(OMe)-OMe leads to Z-L-Asu(OMe)-OH and Z-D-Asu(OMe)-OMe. Subsequent saponifications yield Z-L-Asu-OH and Z-D-Asu-OH. The enzymatic alpha-ester hydrolysis was also achieved by subtilisin BPN' in organic solvent with low water content.
