Definition of cscB

• Curated sequence P30000: Sucrose permease; Sucrose transport protein. Sucrose:H+ symporter, CscB, also transports maltose (Peng et al. 2009). CscB recognizes not just sucrose but also fructose and lactulose, but glucopyranosides are not transported and do not inhibit sucrose transport
• UniProt sequence Q4KBP0: SubName: Full=Oligosaccharide:H+ symporter family protein {ECO:0000313|EMBL:AAY92507.1};
• Comment: PMID:29808622 report that PFL_3238 (Q4KBP0) is a sucrose permease; it is related to E. coli cscB
