Structurally Distinct Active Sites in the Copper(II)-Substituted Aminopeptidases from \u3cem\u3eAeromonas proteolytica\u3c/em\u3e and \u3cem\u3eEscherichia coli\u3c/em\u3e [PDF]

, 2002
The aminopeptidase from Aeromonas proteolytica (AAP) was titrated with copper, which bound sequentially at two distinct sites. Both the mono- and disubstituted forms of AAP exhibited catalytic hyperactivity relative to the native dizinc enzyme ...

Genetic Parameters and Genome‐Wide Association Studies for Fertility and Reproduction Traits in U.S. Katahdin Sheep Based on the Single‐Step GBLUP Methodology

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Sheep production contributes to a secure and diverse food and fibre supply in the United States, with growing ethnic diversity strengthening demand. Katahdin is a composite hair‐type sheep breed developed in the United States that has become the most popular breed in many regions of the country and the first one to have genomic selection ...

Function of the Signal Peptide and N- and C-terminal Propeptides in the Leucine Aminopeptidase from \u3cem\u3eAeromonas proteolytica\u3c/em\u3e [PDF]

, 2004
The leucine aminopeptidase from Aeromonas proteolytica (also known as Vibrio proteolyticus) (AAP) is a metalloenzyme with broad substrate specificity. The open reading frame (ORF) for AAP encodes a 54 kDa enzyme, however, the extracellular enzyme has a ...

Expression of a barley cystatin gene in maize enhances resistance against phytophagous mites by altering their cysteine-proteases [PDF]

, 2011
Phytocystatins are inhibitors of cysteine-proteases from plants putatively involved in plant defence based on their capability of inhibit heterologous enzymes.

Metallo-aminopeptidase inhibitors

Biochimie, 2010
Aminopeptidases are enzymes that selectively hydrolyze an amino acid residue from the N-terminus of proteins and peptides. They are important for the proper functioning of prokaryotic and eukaryotic cells, but very often are central players in the devastating human diseases like cancer, malaria and diabetes.

Three Decades of China's Bt Cotton: Achievements and Insights

Plant Biotechnology Journal, EarlyView.
ABSTRACT Cotton is a vital natural fibre crop with significant economic value worldwide. In response to the threat of cotton bollworm (Helicoverpa armigera), the China government initiated a research project in 1992 to develop transgenic Bacillus thuringiensis (Bt) cotton.

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.

Identification of a Histidine Metal Ligand in the \u3cem\u3eargE\u3c/em\u3e-Encoded \u3cem\u3eN\u3c/em\u3e-Acetyl-L-Ornithine Deacetylase from \u3cem\u3eEscherichia coli\u3c/em\u3e [PDF]

, 2013
The H355A, H355K, H80A, and H80K mutant enzymes of the argE-encoded N-acetyl-L-ornithine deacetylase (ArgE) from Escherichia coli were prepared, however, only the H355A enzyme was found to be soluble. Kinetic analysis of the Co(II)-loaded H355A exhibited

Tolerance to Phosphorus Deficiency Improves Seed Phytic Acid‐to‐Iron Molar Ratios in Common Bean

Plant, Cell &Environment, EarlyView.
ABSTRACT Although significant advances have been achieved in the biofortification of common beans to overcome deficiencies in Zinc (Zn) and iron (Fe), the mechanisms involved remain poorly understood. We thus explored the relationships between phosphorus nutrition and Zn and Fe accumulation in four bean genotypes (Edar, Nizok, Colorado and Chimbolos ...

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
