Peptide bond synthesis catalyzed by thermolysin

Journal of Biochemistry
T Oka, K Morihara


The coupling between Cbz-Phe-OH and Leu-NH2 catalyzed by thermolysin was examined under various experimental conditions. The highest yield (ca. 80%) was obtained in the reaction mixture containing 0.05 M each of the carboxyl and amine components and 10 muM enzyme at pH 7 and 37 degrees C for 5 h. The reactivity was ca. 100 times higher than that of alpha-chymotrypsin. Amino acid derivatives or peptides were useful as amine components, though a hydrophobic or bulky amino acid residue was required at the N-terminal position. Strict stereospecificity was observed at this position. A hydrophobic or bulky amino acid residue occupying the C-terminal position of carboxyl components was also favorable for synthesis. The specificity requirements for synthesis were the same as those for hydrolysis.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
