Peptide bond formation by aminolysin-A catalysis: A simple approach to enzymatic synthesis of diverse short oligopeptides and biologically active puromycins

A new S9 family aminopeptidase derived from the actinobacterial thermophile Acidothermus cellulolyticus was cloned and engineered into a transaminopeptidase by site-directed mutagenesis of catalytic Ser491 into Cys. The engineered biocatalyst, designated aminolysin-A, can catalyze the formation of peptide bonds to give linear homo-oligopeptides, hetero-dipeptides, and cyclic dipeptides using cost-effective substrates in a one-pot reaction. Aminolysin-A can recognize several C-terminal-modified amino acids, including the l- and d-forms, as acyl donors as well as free amines, including amino acids and puromycin aminonucleoside, as acyl acceptors. The absence of amino acid esters prevents the formation of peptides; therefore, the reaction mechanism involves aminolysis and not a reverse reaction of hydrolysis. The aminolysin system will be a beneficial tool for the preparation of structurally diverse peptide mimetics by a simple approach.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 153-94-6 is helpful to your research. Electric Literature of 153-94-6

Role of hydrogen bonding in excited state intramolecular proton transfer of Indole-7-Carboxaldehyde: A theoretical and experimental study

Excited state intramolecular proton transfer (ESIPT) has been studied in Indole-7-Carboxaldehyde (I7C). DFT, TDDFT, CIS theories with B3LYP/6-311++G (d, p), etc. basis sets have been used to obtain structural parameters and energies of I7C in ground, excited states for cis (Nc), trans (Nt) and zwitterionic (Z) conformers. Photo-physical pathway involving ESIPT from cis (Nc) to zwitterion (Z) agrees well with the dual fluorescence at 451 and 862 nm obtained from computed results and experimental observations. Potential energy surface scan confirms the existence of ESIPT by asymmetric double minima in the excited state pathway along the Reaction Coordinate -N 15-H12 donor.

Activation studies with amines and amino acids of the beta-carbonic anhydrase encoded by the Rv3273 gene from the pathogenic bacterium Mycobacterium tuberculosis

The activation of a beta-class carbonic anhydrase (CAs, EC 4.2.1.1) from Mycobacterium tuberculosis, encoded by the gene Rv3273 (mtCA 3), was investigated using a panel of natural and non-natural amino acids and amines. mtCA 3 was effectively activated by D-DOPA, L-Trp, dopamine and serotonin, with KAs ranging between 8.98 and 12.1 muM. L-His and D-Tyr showed medium potency activating effects, with KAs in the range of 17.6?18.2 muM, whereas other amines and amino acids were relatively ineffective activators, with KAs in the range of 28.9?52.2 muM. As the physiological roles of the three mtCAs present in this pathogen are currently poorly understood and considering that inhibition of these enzymes has strong antibacterial effects, discovering molecules that modulate their enzymatic activity may lead to a better understanding of the factors related to the invasion and colonisation of the host during Mycobacterium tuberculosis infection.

Taking advantage of Co(II) induced enhanced VCD for the fast and sensitive determination of enantiomeric excess

Co(II) induces a large VCD signal enhancement, which overcomes the low sensitivity of VCD and opens new perspectives in quantitative VCD. We used a stereodynamic system, where the analyte determines the chirality of the Co(II) coordination sphere. The strong VCD signals stand out the baseline, which allows for their rapid and accurate quantitation. This lends itself to the first general method for the ee determination of a-amino acids based on vibrational circular dichroism and constitutes a model for the design of sensitive quantitative assays based on VCD.

The effect of membrane surface potential on the permeability of anionic compounds across the apical membrane in human intestinal epithelial (Caco-2) cells

The effect of membrane surface potential of the apical side on the intracellular uptake of ionic compounds was investigated using the human colon adenocarcinoma cell line (Caco-2). The transepithelial transport of indolepropionic acid and tryptamine was consistent with the uptake behavior shown by rat intestinal brush-border membrane (BBM) vesicles. Imipramine, which diminished the negative charge of the membrane surface (for both Caco- 2 and BBM), acted to increase the uptake of the anionic compounds, indolepropionic acid and ceftibuten, and to decrease that of tryptamine (cationic compound) by both the Caco-2 monolayer and the intestinal BBM vesicles at a pH of 7.5. These results suggest that the effects of membrane surface potential on the permeability of ionic compounds were detectable on the Caco-2 cell line as well as the BBM vesicles. On the other hand, the inhibition of H+-linked transport and the stimulation of the surface charge- regulated uptake of ceftibuten have occurred simultaneously on the Caco-2 cell line in the presence of imipramine. It seems that the membrane surface charge (negative) plays an important role in the transport process of ionic compounds across the intestinal epithelium.
