DescriptionArginine (abbreviated as Arg or R) is an alpha-amino acid. The L-isomer is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. It is classified as a polar, basic amino acid, because of the positively charged nature of the guanidino-alkyl side chain. With a pKa of 12.5, arginine is a positively amino acid at all physiological pHs. The first five steps of arginine biosynthesis in S. cerevisiae take place in the mitochondrion. This part of the pathway is known as the acetylated derivatives cycle because the acetyl group that is added to L-glutamate in the first step of the pathway is recycled via N-acetylglutamate generated in the fifth step. The enzymes that catalyze the second and third steps are encoded by a single gene (ARG5,6) that is translated into a pre-protein which is imported into mitochondria and cleaved there to yield two enzymes, N-acetylglutamate kinase and N-acetylglutamyl-phosphate reductase. These enzymes form a complex with each other and with N-acetylglutamate synthase, the first enzyme in the pathway, which may have implications for regulation of their activity. The mitochondrial steps of the arginine biosynthesis pathway result in the formation of ornithine, which is exported to the cytoplasm by the transporter Ort1p. In the cytoplasm, L-ornithine is converted to L-arginine in three reactions mediated by ornithine carbamoyltransferase, arginosuccinate synthase, and argininosuccinate lyase. The catabolism of arginine begins within the context of the urea cycle. It is hydrolyzed to urea and ornithine by arginase.
