The enhanced pigmentation in purine biosynthetic purN, purH, purD, or purA mutants is likely caused by increased expression of sigB. The relationship between colony pigment, virulence and drug resistance is still unknown. Therefore, the staphyloxanthin biosynthesis pathway is a potential target to treat S.
