1.B.14.6.1
SusC receptor/porin for maltooligosaccharides (up to maltoheptaose). Forms a complex with and functions with SusD porin (TC# 8.A.46.1.1) as well as SusE and SusF porins (TC#s 1.B.38.1.1 and 1.2) as well as the SusG α-amylase (TC#8.A.9.1.3).  These proteins are all involved in starch utilization (Shipman et al. 2000; Reeves et al. 1997; Cho and Salyers 2001; Foley et al. 2018).
