Entry
EC 7.5.2.3                  Enzyme                                 

Name
ABC-type beta-glucan transporter;
beta-glucan-transporting ATPase
Class
Translocases;
Catalysing the translocation of carbohydrates and their derivatives;
Linked to the hydrolysis of a nucleoside triphosphate
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
ATP [CPD:C00002];
H2O [CPD:C00001];
beta-glucan[side 1]
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
