NATE-0103
Description
Carboxypeptidase C (EC 3.4.16.5, carboxypeptidase Y, serine carboxypeptidase I, cathepsin A, lysosomal protective protein, deamidase, lysosomal carboxypeptidase A, phaseolin) is an enzyme. This enzyme is a carboxypeptidase with optimum activity at pH 4.5-6.0. It is inhibited by diisopropyl fluorophosphate.
Abbr
Carboxypeptidase Y, Native (Baker's Yeast (S. cerevisiae))
Alias
cathepsin A; deamidase
Species
Baker's yeast (S. cerevisiae)
Form
lyophilized powder
Enzyme Commission Number
EC 3.4.16.5
Bio-activity
> 50 units/mg protein
CAS No.
9046-67-7
Composition
Protein, > 75% E1%/280
Unit Definition
One unit will hydrolyze 1.0 μmole of N-CBZ-Phe-Ala to N-CBZ-L-phenylalanine and L-alanine per min at pH 6.75 at 25°C, based on EM/230 = 191.5.
Applications
Carboxypeptidase Y has a broad specificity and is stable in urea. Hence, this enzyme is not like other carboxypeptidases and can be used for sequence analysis. Due to its amidase action, this enzyme might be applied to the sequence analysis of peptides having amidated COOH-terminal groups such as oxytocin and vasopressin.
