Webb6 mars 2024 · Aspartic acid (Asp/D) is a non-essential amino acid with a carboxyl group in its Rgroup. It is readily produced by transamination of oxaloacetate. With a pKa of 3.9, aspartic acid’s side chain is negatively charged at physiological pH. Aspartic acid is specified in the genetic code by the codons GAU and GAC. WebbHypoxia-inducible factor-1α (HIF1α) can suppress tumor cell proliferation. Here, we discovered that HIF1α acts as a direct repressor of aspartate biosynthesis involving the suppression of several key aspartate-producing proteins, including cytosolic glutamic-oxaloacetic transaminase-1 (GOT1) and mitochondrial GOT2. Accordingly, HIF1α….

WebbThe two amino acids in this group are aspartic acid and glutamic acid. Each has a carboxylic acid on its side chain that gives it acidic (proton-donating) properties.
