Abstract
Certain tryptophan auxotrophs of Escherichia coli form a defective A protein, one of the components of the tryptophan synthetase enzyme system. Examination of suppressed mutant of one such strain reveals that, in addition to the altered protein characteristic of the unsuppressed mutant, an A protein with normal catalytic activity is present. Hypotheses for the formation of the 2nd A protein are discussed.This publication has 10 references indexed in Scilit:
