A novel alpha-ketoglutaric semialdehyde dehydrogenase: evolutionary insight into an alternative pathway of bacterial L-arabinose metabolism.
Azospirillum brasilense possesses an alternative pathway of l-arabinose metabolism, which is different from the known bacterial and fungal pathways. In a previous paper (Watanabe, S., Kodaki, T., and Makino, K. (2006) J. Biol. Chem. 281, 2612-2623), we identified and characterized l-arabinose 1-dehydrogenase, which catalyzes the first reaction step in this pathway, and we cloned the correspondi...
متن کاملPurification studies of tyrosine-alpha-ketoglutaric acid transaminase.
Recent studies in vitro of tyrosine metabolism have revealed the distribution and the r&e of the tyrosine-a-ketoglutaric acid transaminase system (l-8). In certain of these studies the obligatory rBle of this transaminase as a first step in the conversion of tyrosine to homogentisic acid has been indicated (6-S). The present study is concerned with the partial purification of dog liver tyrosine...
متن کاملHuman Mutations Affecting Branched Chain Α -ketoacid Dehydrogenase
Maple syrup urine disease results from defective function of the branched chain α-ketoacid dehydrogenase complex [BCKD] within the matrix of the mitochondria. This disorder in humans is inherited as an autosomal recessive trait with an incidence of 1 in 150,000 live-births in the general population and 1/176 for the Mennonite population. Over 50 different causal mutations are known to exist sca...
متن کاملThe α-ketoglutarate dehydrogenase complex in cancer metabolic plasticity
Deregulated metabolism is a well-established hallmark of cancer. At the hub of various metabolic pathways deeply integrated within mitochondrial functions, the α-ketoglutarate dehydrogenase complex represents a major modulator of electron transport chain activity and tricarboxylic acid cycle (TCA) flux, and is a pivotal enzyme in the metabolic reprogramming following a cancer cell's change in b...
متن کاملInactivation and reactivation of the mitochondrial α-ketoglutarate dehydrogenase complex.
Reduced brain metabolism is an invariant feature of Alzheimer Disease (AD) that is highly correlated to the decline in brain functions. Decreased activities of key tricarboxylic acid cycle (TCA) cycle enzymes may underlie this abnormality and are highly correlated to the clinical state of the patient. The activity of the α-ketoglutarate dehydrogenase complex (KGDHC), an arguably rate-limiting e...
