Structure-Function and Industrial Relevance of Bacterial Aminopeptidase P

, 2021
Aminopeptidase P (APPro, E.C 3.4.11.9) cleaves N-terminal amino acids from peptides and proteins where the penultimate residue is proline. This metal-ion-dependent enzyme shares a similar fold, catalytic mechanism, and substrate specificity with ...

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications

Journal of the Chinese Chemical Society, EarlyView.
This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...

Elevated Aminopeptidase P Attenuates Cerebral Arterial Responses to Bradykinin in Fawn-Hooded Hypertensive Rats. [PDF]

PLoS ONE, 2015
Cerebral arterial myogenic and autoregulatory responses are impaired in Fawn Hooded hypertensive (FHH) rats. Cerebral autoregulatory responses are restored in the congenic rat strain in which a segment of chromosome 1 from the Brown Norway (BN) rat was ...

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

Evolution of free amino acids and volatile compounds in dry‐cured fermented 'salchichón' sausages superficially inoculated with different molds

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Surface molds contribute to flavor development in dry‐cured fermented sausages through their effects on proteolysis, amino acid catabolism, and volatile compound formation. This study evaluated the influence of Aspergillus oryzae, Penicillium camemberti, Penicillium roqueforti and Penicillium nalgiovense on the evolution of free ...

Carbon‐Fixing Bacterial Network Complexity Mediates Soil Multifunctionality in a Panax notoginseng‐Pinus armandii Agroforestry System

Land Degradation &Development, EarlyView.
ABSTRACT Autotrophic carbon‐fixing bacteria (CFB) are central contributors to soil carbon sequestration and biogeochemical carbon cycling in agroforestry ecosystems and can act as reliable biological indicators for evaluating agroforestry ecosystem sustainability.

Mechanisms of HIV Protein Degradation into Epitopes: Implications for Vaccine Design

Viruses, 2014
The degradation of HIV-derived proteins into epitopes displayed by MHC-I or MHC-II are the first events leading to the priming of HIV-specific immune responses and to the recognition of infected cells.

Deep Straw Incorporation With Supplemental Fertilization Improves Subsoil Quality and Maize Productivity

Land Degradation &Development, EarlyView.
ABSTRACT Deep straw incorporation is widely advocated for enhancing crop yields and improving agroecosystem functions and services. However, how this practice interacts with different fertilization strategies synergistically to influence soil quality and maize productivity remains unclear.

Type II Secretion-Dependent Aminopeptidase LapA and Acyltransferase PlaC Are Redundant for Nutrient Acquisition during Legionella pneumophila Intracellular Infection of Amoebas

mBio, 2018
Legionella pneumophila genes encoding LapA, LapB, and PlaC were identified as the most highly upregulated type II secretion (T2S) genes during infection of Acanthamoeba castellanii, although these genes had been considered dispensable on the basis of the
