SusE and SusF are two outer membrane proteins composed of tandem starch specific carbohydrate binding modules (CBMs) with no enzymatic activity. They are are likely to play an important role in starch metabolism in Bacteroides. It has been speculated that they could compete for starch in the human intestinal tract by sequestering starch at the bacterial surface and away from competitors [1]. SusE has higher affinity for starch compared to SusF. SusE contains two starch specific CBMs whereas SusF contains three. This entry represents the two SusE and the second and third SusF CBMs.	Domain

This domain is found in the Outer membrane protein SusF from Bacteroides thetaiotaomicron and related proteins. SusF is a multidomain protein and contains three starch specific carbohydrate binding modules (CBMs). Each of this CBMs differ in the way it binds starch. Each binding site has a unique starch preference that probably enable these proteins to interact with different regions of starch or its breakdown products [1]. This entry represents the first of the tandem CBMs.	Domain
