  • We have shown that the bldD gene of Streptomyces coelicolor, while required for antibiotic production and morphological differentiation, is not essential for viability. We have also demonstrated that BldD forms a higher order complex both in solution and when bound to target DNA. Purified BldD exists in three forms in solution, as a tetramer, dimer and monomer, but only in the dimeric form when bound to its own promoter/operator.
