A second and unusual pucBA operon of Rhodobacter sphaeroides 2.4.1: genetics and function of the encoded polypeptides.

Journal of bacteriology - 1 Oct 2003

Abstract excerpt

A new operon (designated the puc2BA operon) displaying a high degree of similarity to the original pucBA genes of Rhodobacter sphaeroides 2.4.1 (designated puc1) was identified and studied genetically and biochemically. The puc2B-encoded polypeptide is predicted to exhibit 94% identity with the original beta-apoprotein. The puc2A-encoded polypeptide is predicted to be much larger (263 amino acids) than the...
