Abstract

SUMMARY: Proline suppressor mutant -19 was analysed for arginase and ornithine δ-transaminase (OTA) activity. Both enzymes are constitutively produced by this mutant. Five other suppressor loci not linked with -19 or to each other are involved in regulation of the two enzymes.

A mutant showing no OTA activity was isolated. Properties of this mutant and its effect in various strains of the type were studied.
