3.A.1.1.34
The arabinosaccharide transporter AraNPQMsmX. Transports α-1,5-arabinooligosaccharides, at least up to four L-arabinosyl units; the key transporter for α-1,5-arabinotriose and α-1,5-arabinotetraose, but not for α-1,5-arabinobiose which is transported by AraE. MsmX is also used by the MdxEFG-MsmX system (3.A.1.1.36) (Ferreira and Sá-Nogueira, 2010). Involved in the uptake of pectin oligosaccharides with either MsmX or YurJ as the ATPase (Ferreira et al. 2017).
