Carboxypeptidase A from bovine pancreas has been used in a study to investigate the expression of a soluble and activatable form of bovine procarboxypeptidase A in Escherichia coli. Carboxypeptidase A from bovine pancreas has also been used in a study to investigate the isolation and partial characterization of precursor forms of ostrich carboxypeptidase.
The enzyme from Sigma has been used as a comparison to study the specificity of Metarhizium anisopliae carboxypeptidase A (MeCPA). MeCPA had been genetically engineered to facilitate the removal of polyhistidine tags from the C-termini of recombinant proteins. It has also been used to de-tyrosinate α-tubulin, in vitro, in order to induce high affinity to ethyl-N-phenylcarbamate (EPC) sepharose.
생화학적/생리학적 작용
Carboxypeptidase as isolated from bovine pancreas glands is a metalloenzyme that contains 1 g atom of zinc per mole of protein. It catalyzes the hydrolysis of the carboxyl-terminal peptide bond in peptides and proteins. It is primarily specific to aromatic and hydrophobic side chains such as phenylalanine, tryptophan or leucine. The enzyme also exhibits esterase activity. It is inhibited by beta-phenylpropionate and indole acetate.

Auxin controls the orientation of cortical microtubules in maize coleoptile segments. We used tyrosinylated alpha-tubulin as a marker to assess auxin-dependent changes in microtubule turnover. Auxin-induced tyrosinylated alpha-tubulin, correlated with an elevated sensitivity of growth to antimicrotubular compounds such as

Alpha tubulin comprises a C-terminal tyrosine residue, which is subject to cyclic removal from the peptide chain by a still uncharacterized carboxypeptidase and re-addition to the chain by a tubulin tyrosine ligase. We have shown in different animal or human

Carboxypeptidases may serve as tools for removal of C-terminal affinity tags. In the present study, we describe the expression and purification of an A-type carboxypeptidase from the fungal pathogen Metarhizium anisopliae (MeCPA) that has been genetically engineered to facilitate the

Excessive replication of Saccharomyces cerevisiae Ty1 retrotransposons is regulated by Copy Number Control, a process requiring the p22/p18 protein produced from a sub-genomic transcript initiated within Ty1 GAG. In retrotransposition, Gag performs the capsid functions required for replication and re-integration.
