IntEnz Enzyme Nomenclature


Accepted name:
ABC-type capsular-polysaccharide transporter
Other name:
capsular-polysaccharide-transporting ATPase
Systematic name:
ATP phosphohydrolase (ABC-type, capsular-polysaccharide-exporting)



ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains. Does not undergo phosphorylation during the transport process. An enzyme that exports capsular polysaccharide in Gram-negative bacteria. Formerly EC
