This study was designed to investigate a postulated relationship between vitamin B-12 and leucine metabolism in mature domestic chickens. Plasma amino acid analysis revealed the presence of beta-leucine at a concentration of 60 to 80 mumol/l. After 425 d on

Circulating levels of beta-leucine are elevated in the cobalamin-deficient state of pernicious anemia. Levels of leucine, on the other hand, are much lower. It is proposed that leucine 2,3-aminomutase, the cobalamin-dependent enzyme that catalyzes the interconversion of leucine and beta-leucine
