3.A.1.1.2
The galactooligosaccharide (transports the di, tri and tetrasaccharides) uptake porter GanOPQ (GanSPQ; MalEFG) functioning with the energizing ATPase MsmX (see 3.A.1.1.26).  These oligosaccharides are derived from galactans and arabinogalactans, compenents of pectins in plant cell walls (Watzlawick et al. 2016).

Accession Number:O07011

Molecular Weight:31305.00
Species:Bacillus subtilis [1423]
Number of TMSs:6
Location1 / Topology2 / Orientation3: Cell membrane1 / Multi-pass membrane protein2
Substrate galactooligosaccharide
