Descripción general
Carboxypeptidase A-agarose product is prepared by the immobilization of carboxypeptidase A, originally isolated from the bovine pancreas, to activated 4% crosslinked beaded agarose.
Acciones bioquímicas o fisiológicas
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 β-phenylpropionate and indole acetate.
Carboxypeptidase A is attached covalently to agarose or aldehyde and is effective for immobilization studies.
Definición de unidad
One unit will hydrolyze 1.0 μmole of hippuryl-L-phenylalanine per min at pH 7.5 at 25 °C.

We used the opportunities afforded by the zebrafish to determine upstream pathways regulating mast cell development in vivo and identify their cellular origin. Colocalization studies demonstrated zebrafish notch receptor expression in cells expressing carboxypeptidase A5 (cpa5), a zebrafish mast cell-specific

This paper proposes a method to enzymatically treat poor-quality cocoa almonds (known as "slate") to ensure the formation of chocolate flavor precursors. The production of flavor precursors improves the quality of these almonds, which are usually responsible for the low

Promiscuity, the basis for the evolution of new functions through 'tinkering' of residues in the vicinity of the catalytic site, is yet to be quantitatively defined. We present a computational method Promiscuity Indices Estimator (PROMISE)--based on signatures derived from the

Water is an integral part of protein complexes. It shapes protein binding sites by filling cavities and it bridges local contacts by hydrogen bonds. However, water molecules are usually not included in protein interface models in the past, and few

Pancreatic cancer has a dismal prognosis because it is often diagnosed at an advanced stage. Therefore, serological biomarkers are eagerly sought for early detection. The digestive enzyme pro-carboxypeptidase A (PCPA) may be able to fill this role. The purpose of
