PREFERENTIAL SYNTHESIS OF ALPHA-AMYLASE BY BACILLUS STEAROTHERMOPHILUS IN THE PRESENCE OF 5-METHYL-TRYPTOPHAN.

abstract：:Examination of the ilvF locus at 54 min on the Escherichia coli K-12 chromosome revealed that it is a cryptic gene for expression of a valine-resistant acetohydroxy acid synthase (acetolactate synthase; EC 4.1.3.18) distinct from previously reported isozymes. A spontaneous mutation, ilvF663, yielded IlvF+ enzyme activ...
