In search of databases, the deduced products of sanP, sanQ, sanR, sanS, sanT and sanU show highest similarity to those of nikP2, nikQ, nikR, nikS, nikT and nikU of S. tendae respectively. In comparison with the proteins of identified function, it is indicated that sanP encodes a thioesterase, sanQ encodes a cytochrome P450, sanR encodes a uracil phosphoribosyltransferase, sanS encodes a carboxylase, sanT encodes a histidinol-phosphate aminotransferase and sanU encodes a mutase.
