Second domain of the ATP-binding cassette component of monosaccharide transport system
This family represents domain II of the carbohydrate uptake proteins that transport only monosaccharides (Monos). The Carb_Monos family is involved in the uptake of monosaccharides, such as pentoses (such as xylose, arabinose, and ribose) and hexoses (such as xylose, arabinose, and ribose), that cannot be broken down to simple sugars by hydrolysis. In members of Carb_Monos family the single hydrophobic gene product forms a homodimer, while the ABC protein represents a fusion of two nucleotide-binding domains. However, it is assumed that two copies of the ABC domains are present in the assembled transporter.
