Abstract excerpt

Rhodovulum (Rhv.) sulfidophilum, unlike other nonsulfur purple bacteria, is able to synthesize the peripheral antenna complex even under fully aerobic conditions in the dark. We have obtained strong evidence that Rhv. sulfidophilum encodes only one copy of the puc operon, comprising pucB, pucA and pucC. pucB and pucA encode the beta- and alpha-polypeptides. The third ORF (pucC), downstream of pucA, has a strong...
