PANTOTHENIC ACID STUDIES VIII. (PAC)

Microbic Decomposition of Pantothenic Acid.

The metabolism of pantothenic acid.

The formulation of this pathway was based on: (a) the finding that cysteine supplies the sulfur-containing moiety of CoA (3,4); (b) the activities of pantetheine and pantothenylcysteine as growth factors for Acetobacter suboxydans (4-6) and Lactobacillus helveticus (7); (c) the presence of enzymes in these two organisms and also in Lactobacillus bulgur&s which decarboxylate pantothenylcysteine ...

Hematopoiesis in pantothenic acid-deficient rats.

Pantothenic acid synthesis by smooth Brucella abortus.

The relationship between formation of exogenous alanine and the establishment of nonsmooth variants in originally smooth cultures of Brucella abortus strains has been clearly demonstrated (Goodlow et al., 1950). Furthermore, the addition of D-alanine to smooth cultures in synthetic medium (Gerhardt and Wilson, 1948) results in earlier establishment of nonsmooth cells (Goodlow et al., 1951). Sub...

Pantothenic acid deficiency induced in human subjects.

Bean and Hodges (1) gave a preliminary report of four young men in whom clinical disorders and metabolic faults were induced by a "diet" devoid of pantothenic acid, with omega-methylpantothenic acid, a vitamin antagonist (Figure 1). It is proposed here to describe details of the experiments, results, and some interpretations. The background for using molecular antagonists (2, 3) in human nutrit...
