Some selected amino acids, in particular L-aspartic acid (L-Asp) and L-histidine (L-His), can function as leaving group during polymerase-catalyzed incorporation of deoxyadenosine monophosphate (dAMP) in DNA. Although L-Asp-dAMP and L-His-dAMP bind, most probably, in a different way in the active site of the enzyme, aspartic acid and histidine can be considered as mimics of the pyrophosphate mo...
The occurrence of free D-amino acids and aspartate racemases in several hyperthermophilic archaea was investigated. Aspartic acid in all the hyperthermophilic archaea was highly racemized. The ratio of D-aspartic acid to total aspartic acid was in the range of 43.0 to 49.1%. The crude extracts of the hyperthermophiles exhibited aspartate racemase activity at 70 degrees C, and aspartate racemase...
This study was conducted with the aim of showing effect injecting D-Aspartic acid on characteristics semen, for Period 15/7/2021 until 15/10/2021 in animal farm/ Ruminant Hall Animal Production Department /College Agriculture / University Diyala. include 12 male Shami goat aged (1-1.3) years, an average weight (35-38) kg, were divided randomly to four equal groups (3/ group): first a control gr...
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...
