Minimizing amino acid catabolism decreases amino acid requirements.
The processes of natural selection shape the efficiency of nutrient use by animals, with some being especially thrifty while others are wasteful. An examination of the widely divergent amino acid economies of different species vividly illustrates this basic nutritional principle. The domestic cat evolved as a carnivore and has a very high maintenance requirement for dietary amino acids. The cat...
متن کاملRegulation of branched-chain amino acid catabolism.
Catabolism of the branched-chain amino acids is regulated in part at the step catalyzed by the branched-chain alpha-ketoacid dehydrogenase complex. Previous work suggests both short-term and long-term control mechanisms are involved in regulation of the kinase responsible for phosphorylation and inactivation of the branched-chain alpha-ketoacid dehydrogenase complex. Recent work of this laborat...
متن کاملBranched-chain amino acid catabolism in bacteria.
The enzymatic conversions necessary for the catabolism of branched-chain amino acids have been reported to occur in a wide variety of bacteria. However, most studies have been done using several species of Pseudomonas. Pseudomonads are richly endowed with extraordinary nutritional versatility, which enables them to catabolize a diverse array of organic compounds (64), including the branchedchai...
متن کاملd-Amino Acid Catabolism Is Common Among Soil-Dwelling Bacteria
Soil and rhizosphere environments were examined in order to determine the identity and relative abundance of bacteria that catabolize d- and l-amino acids as the sole source of carbon and nitrogen. All substrates were readily catabolized by bacteria from both environments, with most d-amino acids giving similar CFU counts to their l-amino acid counterparts. CFU count ratios between l- and d-ami...
متن کاملAmino Acid Catabolism in Alzheimer's Disease Brain: Friend or Foe?
There is a dire need to discover new targets for Alzheimer's disease (AD) drug development. Decreased neuronal glucose metabolism that occurs in AD brain could play a central role in disease progression. Little is known about the compensatory neuronal changes that occur to attempt to maintain energy homeostasis. In this review using the PubMed literature database, we summarize evidence that ami...
