FunctionARAF_ECOLI Involved in the high-affinity L-arabinose membrane transport system. Binds with high affinity to arabinose, but can also bind D-galactose (approximately 2-fold reduction) and D-fucose (approximately 40-fold reduction). Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. |
