Processing of pro-sigma(K) in the mother cell compartment of sporulating Bacillus subtilis involves SpoIVFB and is governed by a signal from the forespore. SpoIVFB has an HEXXH motif characteristic of metalloproteases embedded in one of its transmembrane segments. Several conservative single amino acid changes in the HEXXH motif abolished function. However, changing the glutamic acid residue to...
In the present study, we identified free amino acid (FAA) contents and chemical composition in four populations of Salmo trutta macrostigma living in Mediterranean region of Turkey. In addition, taste impacts of FAAs were evaluated by taste active values. Moisture, protein, fat and ash content were found in the ranges of 75.49 - 79.59 %, 16.94 - 19.97 %, 1.58 - 3.75 % and, 1.39 - 1.56 %, respec...
Optically pure â,â-dimethylated amino acid building blocks with functionalized side chains have been prepared from D-aspartic acid. The dimethylation was accomplished by regioselective dialkylation of 9-phenylfluorenyl (PhFl)-protected aspartate diesters. The bulk of the PhFl protecting group also allowed for a variety of functional group manipulations to be carried out on the side chain withou...
Iron (Fe) is an essential micronutrient for plant growth and development, and its reduced bioavailability strongly impairs mitochondrial functionality. In this work, the metabolic adjustment in the rice (Oryza sativa) mitochondrial Fe transporter knockdown mutant (mit-2) was analysed. Biochemical characterization of purified mitochondria from rice roots showed alteration in the respiratory chai...
securigera securidaca (l.) degen & dorfl grows in different parts of iran. the seeds of the species are used in iranian folk medicine as an anti-diabetic agent. many studies have established hypoglycemic effects of amino acids and in the present investigation, amino acids of securigera securidaca seeds have been evaluated. the ground seeds were extracted using petroleum ether, hot ethanol a...
INTRODUCTION Non-enzymatic glycation of proteins has been implicated in various diabetic complications and age-related disorders. Proteins undergo glycation at the N-terminus or at the epsilon-amino group of lysine residues. The observation that only a fraction of all lysine residues undergo glycation indicates the role of the immediate chemical environment in the glycation reaction. Here we ha...
Introduction: Non-enzymatic glycation of proteins has been implicated in various diabetic complications and age-related disorders. Proteins undergo glycation at the N-terminus or at the O-amino group of lysine residues. The observation that only a fraction of all lysine residues undergo glycation indicates the role of the immediate chemical environment in the glycation reaction. Here we have co...
