摘要

ARGRI, ARGRII, and ARGRIII regulatory proteins control the expression of arginine anabolic and catabolic genes in Saccharomyces cerevisiae. We show here that they are also required in vitro to observe a protein-DNA complex with the promoter of the ARG5,6 gene. The specific binding of ARGR proteins in vitro is stimulated by arginine. Antibodies raised against a synthetic MCM1 polypeptide retard the migration of ARGR-DNA complex on gel mobility shift assays. This result suggests that MCM1 could be an additional regulatory element of arginine metabolism.
