Studies on the specificity of acetylaminoacylpeptide hydrolase [PDF]

open access: yesProtein Science, 1994
AbstractIn a continuing attempt to explore the types of specificity determinants that may affect protein‐protein (peptide) interactions, a number of short (2‐5 residues) acetylated peptides have been compared as substrates for the enzyme acetylaminoacyl‐peptide hydrolase (EC 3.4.19.1).

Peptide hydrolases in senescing ragi leaves

open access: yesBiologia Plantarum, 1987
Two peptide hydrolases — one active at pH 7.0 and the other at pH 3.4 (SH-dependent) were detected in ragi (Eleusine coracana Gaertn. cv. PR 202) leaves. The absolute activities of both acid and neutral peptide hydrolases were move or less stable in attached leaves and exhibited a mild rise in excised leaves, whereas the specific activities exhibited a

Peptide Hydrolases of Propionibacteria: Effect of pH and Temperature

open access: yesJournal of Food Protection, 1990
A comparative study of the activity of peptidases belonging to the four classic propionibacteria species cultured in milk was carried out at different values of pH and temperature. Leucine aminopeptidase and proline iminopeptidase showed greater activity in Propionibacterium freudenreichii than in the other species studied. With the single exception of

Isolation and Characterisation of Peptide Hydrolases from the Maize Root [PDF]

open access: yesEuropean Journal of Biochemistry, 1979
The maize root has two main proteinase and carboxypeptidase components. Proteinase I and carboxypeptidase I, which predominate in older plants, appear to have a serine group at their active sites and have been estimated to have molecular weights of approximately 54000 and 77000 respectively.

A GMR enzymatic assay for quantifying nuclease and peptidase activity

open access: yesFrontiers in Bioengineering and Biotechnology
Hydrolytic enzymes play crucial roles in cellular processes, and dysregulation of their activities is implicated in various physiological and pathological conditions. These enzymes cleave substrates such as peptide bonds, phosphodiester bonds, glycosidic
