1.B.38.4.2
Outer membrane protein, SusF, of 485 aas and 1 N-terminal TMS.  The protein has an N-terminal DUF5115 domain followed by two C-terminal CBM-SusEF-like domains. SusF mediates starch-binding (or maltooligosaccharde-binding) before transport into the periplasm for further degradation. SusE and SusF do not constitute the major starch-binding proteins in the starch degradative pathway. SusF has lower affinity for starch compared to SusE (Shipman et al. 2000). The 3-d structure of the complex has been determined (Cameron et al. 2012). The SusCDEFG complex in the outer membrane is described in more detail in TC# 1.B.38.4.1 (Foley et al. 2018).
