The effect of the bacteriocin lacticin 3147 on the branched-chain amino acid transamination by Lactococcus lactis IFPL359 was investigated. The bacteriocin provokes membrane permeabilisation of the cells, rendering them non-viable but metabolically active. Free diffusion of amino acids into the

A simple and highly sensitive high-performance liquid chromatographic (HPLC) method for the determination of alpha-keto acids in human serum and urine is described. In an acidic solution, twelve species of alpha-keto acids examined were converted by reaction with 1,2-diamino-4,5-methylenedioxy-benzene into

Whole cell extracts of culture epimastigotes of Trypanosoma cruzi (Tulahuén strain) have alpha-hydroxyacid dehydrogenase activity which catalyzes the NAD-linked reaction alpha-ketoacid in equilibrium with alpha-hydroxyacid, with a variety of substrates. Two molecular forms of the enzyme have been separated by
