| Abstract: | 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. |
