Certain strains of "S. haemolyticus" are capable of producing a capsular polysaccharide (CP). "S. haemolyticus" strain JCSC1435 contains a capsule operon located within the “oriC environ”. This operon contains 13 ORFs in a 14,652-bp region and is referred to as the "capsh" locus. The first seven genes of "capsh" ("capAsh" through "capGsh") are homologous to the "S. aureus" "cap5" or "cap8" locus. However, "capH" through "capM" are unique to "S. haemolyticus", and this region encodes enzymes for a unique trideoxy sugar residue that is N-acylated by aspartic acid.
