Summary

Our group investigates regulation of gene expression in bacteria. More specifically, since 1956 we have studied the regulation of arginine biosynthesis in Escherichia coli. Recently, we isolated and characterized the arginine repressor protein and are now determining its structure. We found this protein to be unusual in several respects: 1) It is a hexamer in solution; 2) its interaction with operator DNA differs from that of other repressors; and 3) it is required not only for enzyme regulation of arginine biosynthesis but for stable maintenance of certain plasmids.

We also study the initiation of plasmid replication, regulation of enterotoxin production, and properties of a novel retroelement in E. coli that uses reverse transcriptase to produce molecules consisting of single-stranded DNA covalently linked to RNA-molecules we found to be mutagenic.
