Tryptic digestion of immobilized D‐amino acid oxidase

FEBS Letters, 1978
Received 20 December 1977 1. Introduction The activity of an enzyme is dependent on its conformation and on the structure of its active site. Chemical modification and specific labelling of an active site are useful techniques for the analysis on its structure; however, they often result in undesirable changes in enzyme conformation.

Nutritional quality of the protein of Vigna unguiculata L. Walp and its protein isolate

Revista Ciência Agronômica
A protein's true digestibility and amino acid composition are important characteristics for its nutritional characterisation. This study determined the true digestibility of the protein from cowpea (Vigna unguiculata L. Walp.) and of its protein isolate,

Apparent and True Digestibility of Amino Acids of Meat Cum Bone Meal and Fish Meal in Caecectomized Roosters

The Journal of Poultry Science, 2007
The apparent and true amino acid digestibilities of silver fish meal and meat cum bone meal were determined using adult caecectomized roosters. Each test ingredient was offered to six caecectomized and six intact cockerels individually.

The pig is an excellent model to determine amino acid digestibility of human foods and to generate data needed to meet human amino acid requirements

Frontiers in Nutrition
The protein value of any food item is determined by the quantity and ileal digestibility of indispensable amino acids in that food. To determine the ileal digestibility of amino acids, an animal model needs to be used, and the pig is the preferred model ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Fermentation of Peanut Slurry with Lactococcus lactis Species, Leuconostoc and Propionibacterium freudenreichii subsp. globosum Enhanced Protein Digestibility

Foods, 2023
Peanuts contain nutritionally relevant levels of protein, yet are poorly digestible. Fermentation is a promising technique to boost legume protein quality, but its effect on the protein quality of raw peanuts has not been investigated.
