COFACTOR REQUIREMENTS FOR ENZYMATIC DENlTRIFICATION
The reduction of nitrite to nitric oxide has been shown to require DPN or TPN, FAD or FMN,’ copper, and iron as electron carriers. This was determined by the stimulation of nitrite disappearance as well as by increased nitric oxide formation. Evidence was also presented indicating that the reduction of NO to Nz was stimulated by the same cofactors. The evidence was based on the stimulation of N...
متن کاملThe cofactor requirements of sarcosine oxidase.
It has been established that the enzyme, sarcosine oxidase, found in the mitochondria of rat liver and elsewhere (I), catalyzes the following over-all reaction (2, 3) : sarcosine + $02 = glycine + serine + HCHO. The cofactor requirements of this reaction have not been established, although Mackenzie (1) has mentioned unpublished results which seemed to indicate that a folic acid deficiency in r...
متن کاملBiotypes of Proteus rettgeri.
Examination of 729 isolates of Proteus rettgeri showed that 674 reacted positively in tests for phenylalanine deamination, indole production, growth on citrate, and acid production from meso-inositol, and negatively for L-ornithine decarboxylation and acid production from lactose, maltose, D-xylose, and L-arabinose. Only 51 isolates differed in one, and four differed in two of these ten reactio...
متن کاملProperties of Crystalline Tryptophanase.
In 1903 Hopkins and Cole (1) identified tryptophan as the source of indole produced by bacterial cultures. The tryptophan-inducible enzyme responsible for this conversion, which is found most commonly in Escherichia coli, was subsequently named tryptophanase by Happold and Hoyle (2). Wood, Gunsalus, and Umbreit (3) showed that tryptophanase catalyzed the stoichiometric conversion of tryptophan ...
متن کاملCofactor Requirements of y=Butyrobetaine Hydroxylase from Rat Liver*
The hydroxylation of y-butyrobetaine (4-trimethylaminobutyrate) to carnitine (3-hydroxy-4-trimethylaminobutyrate) is catalyzed by a soluble enzyme from rat liver which has been partially purified. The enzyme which previously has been shown to require molecular oxygen and ferrous ion has a specific requirement for 2-ketoglutarate. Several reductams stimulate the formation of hydroxylated product...
