BRITE hierarchy
Sysname
ATP phosphohydrolase (ABC-type, beta-glucan-exporting)
Reaction(IUBMB)
ATP + H2O + beta-glucan[side 1] = ADP + phosphate + beta-glucan[side 2]
Substrate
Product
ADP [CPD:
C00008 ];
phosphate [CPD:
C00009 ];
beta-glucan[side 2]
Comment
An ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. An enzyme found in Gram-negative bacteria that exports beta-glucans.
History
EC 7.5.2.3 created 2000 as EC 3.6.3.42, transferred 2018 to EC 7.5.2.3
Orthology
K24819 ATP-binding cassette, subfamily B, beta-glucan exporter
