Degradation of 4-hydroxyphenylacetate by Xanthobacter 124X. Physiological resemblance with other gram-negative bacteria.

Abstract

Xanthobacter 124X when grom on 4-hydroxyphenylacetate was able to hydroxylate this compound yielding homogenisate. Ring fission of this latter compound gave maleylacetoacetate which was isomerized to fumarylacetoacetate. The isomerase involved resembled maleylacetoacetate isomerases in Gram-negative bacteria in that glutathione was required for activity. Fumarate and acetoacetate were both detected as products of the hydrolysis of fumarylacetoacetate.
