Regulation of protein synthesis by branched-chain amino acids.
Historically, amino acids have been viewed as precursors for protein synthesis as well as metabolic substrates. Recently, a new role for amino acids as regulators of mRNA translation has been identified. In this role, they modulate the phosphorylation state of proteins that represent important control points in translation initiation, including the translational repressor 4E-BP1 and the ribosom...
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 کاملRegulation of branched-chain amino acid biosynthesis by alpha-acetolactate decarboxylase in Streptococcus thermophilus.
AIMS To demonstrate the presence of an active alpha-acetolactate decarboxylase in Streptococcus thermophilus and to investigate its physiological function. METHODS AND RESULTS Streptococcus thermophilus CNRZ385 contains a gene encoding an alpha-acetolactate decarboxylase. Comparison of the production of alpha-acetolactate and its decarboxylation products, by the parent strain and an alpha-ace...
متن کاملCharacterization of an Arabidopsis enzyme family that conjugates amino acids to indole-3-acetic acid.
Substantial evidence indicates that amino acid conjugates of indole-3-acetic acid (IAA) function in auxin homeostasis, yet the plant enzymes involved in their biosynthesis have not been identified. We tested whether several Arabidopsis thaliana enzymes that are related to the auxin-induced soybean (Glycine max) GH3 gene product synthesize IAA-amino acid conjugates. In vitro reactions with six r...

The three branched-chain amino acids (BCAAs) are the most hydrophobic of the amino acids and play crucial roles in determining the structures of globular proteins as well as the interaction of the transmembrane domains of membranous proteins with phospholipid bilayers. However, the three BCAAs do not behave identically. In terms of protein secondary structure, valine and isoleucine exhibit a de...
