Phosphotransferase that is responsible for the production of the 3-phosphohydroxyasparaginyl residues found at position 9 in the non-ribosomally synthesized calcium-dependent antibiotic (CDA) derivatives CDA1b and CDA2a/b. It is not known whether the phosphorylation reaction takes place before, during or after peptide assembly. Antibiotic biosynthesis; calcium-dependent antibiotic biosynthesis. Cells produce only the non-phosphorylated variants CDA3b and CDA4b, while S.coelicolor strain A3(2) / 2377 produces D-3-phosphohydroxyasparagine-containing peptide CDA2b as the major product, along with a minor amount of D-3-hydroxyasparagine variants CDA4b and CDA3b.
