ClpB proteins copurify with the anaerobic Escherichia coli reductase.
Two proteins, called alpha and beta 3, copurify with the anaerobic ribonucleotide reductase from Escherichia coli (Eliasson et al. (1990) Proc. Natl. Acad. Sci. U.S.A. 87, 3314-3318). Both are now identified as products of the clpB gene that is presumed to code for a subunit of an ATP dependent protease. The tight associations suggest the possibility that the ClpB proteins are involved in the regulation of the anaerobic reductase.
