CDA is a new chromosomally-determined antibiotic from Streptomyces coelicolor A3(2).
Mutations (cda) leading to non-production of the new calcium-dependent antibiotic (CDA) of Streptomyces coelicolor A3(2) were closely linked on the chromosome. One representative mutation (cda-1) was mapped precisely between nicA and adeC. No cosynthesis of CDA was found in any pairwise combinations of 14 cda mutants. Mutations lacking aerial mycelium (bald mutations), mapping to the four previously described loci (bldA-D), were pleiotropically defective in production of CDA.
