Coenzyme A as growth stimulant for Acetobacter suboxydans.
It had been found that pantothenic acid bound in coenzyme A and its partial degradation products is inactive in the test with Lactobacillus arabinosus.l In this connection a recent report by King, Lecher, and Cheldelin2 was of considerable interest. They isolated from heart muscle a pantothenic acid-containing factor which, with 9. suboxydans, gave a greater and faster growth response than woul...
متن کاملOxidations in Acetobacter suboxydans.
It has been shown that glycerol can be oxidized beyond the dihydroxyacetone (DHA) stage by resting Acetobacter suboxydans cells (1). Through washing and centrifuging of the cells at room temperature, most of the oxidative activity was destroyed, which, however, could be restored by the addition of inorganic phosphate and diphosphopyridine nucleotide (DPN). 2,4-Dinitrophenol (DNP), a phosphate “...
متن کاملOxidations by Acetobacter Suboxydans
Acetobacter suboxydans is known to bring about oxidation of polyhydroxy compounds. The action of the bacterial enzyme is limited, however, to substances with specific configurations. According to the generalization of Bertrand,’ only those hydroxyl groups are oxidized which are situated between a primary hydroxyl group and a secondary one in a cis position. Hann, Tilden, and Hudson,2 in a compa...
متن کاملOxidative dissimilation in Acetobacter suboxydans.
Interest in this laboratory has focused upon the metabolism of the acetic acid bacteria since the superior activity of bound forms of pantothenic acid (PAC) ((1, 2); coenzyme A (3, 4)) over the free vitamin was discovered. The disclosure that pantetheine (Lactobadus bulgaricus factor) is a mercaptan capable of coexisting with an oxidized disulfide form (5) has led to speculation as to whether c...
متن کاملSorbitol dehydrogenases in Acetobacter suboxydans.
It has previously been shown that cell-free extracts of Acetobacter subozydans possess two pathways for the oxidation of sorbitol (1). In the presence of DPN,l fructose is produced; with TPN, sorbose is formed. The primary purpose of this paper is to describe the separation of these two dehydrogenases from each other. The DPN enzyme free from TPN activity has been concentrated about lBfold, whe...
