Digestive enzymes profile of the midgut gland of juvenile painted river prawn (Macrobrachium carcinus)

Aquaculture Reports, 2020
This study assessed the activity of the main digestive enzymes in juveniles of the painted river prawn Macrobrachium carcinus. Prawns reared in 24 m2 tanks at a density of 10 individuals. m−2 for 45 days were fed a commercial diet with 40 % crude protein.

Adipocyte-derived leucine aminopeptidase genotype and response to antihypertensive therapy

BMC Cardiovascular Disorders, 2003
Background Adipocyte-derived leucine aminopeptidase (ALAP) is a recently identified member of the M1 family of zinc-metallopeptidases and is thought to play a role in blood pressure control through inactivation of angiotensin II and/or generation of ...

Soil aminopeptidase activities under 145-year crop rotation and fertility practices in the North Central US

Geoderma, 2023
Aminopeptidases catalyze the hydrolysis of peptides into constituent amino acids and are therefore a key step in nitrogen (N) depolymerization and downstream mineralization. Differences in carbon (C):N as well as sulfur (S) content of amino acids present

An M29 Aminopeptidase from Listeria Monocytogenes Contributes to In Vitro Bacterial Growth but not to Intracellular Infection

Microorganisms, 2020
Aminopeptidases that catalyze the removal of N-terminal residues from polypeptides or proteins are crucial for physiological processes. Here, we explore the biological functions of an M29 family aminopeptidase II from Listeria monocytogenes (LmAmpII). We
