PTS system, sucrose-specific IIBC component; This model represents the fused enzyme II B and C components of the sucrose-specific PTS sugar transporter system. Sucrose is converted to sucrose-6-phosphate in the process of translocation into the cell. Some of these transporters lack their own IIA domains and instead use the glucose IIA protein (IIAglc or Crr). The exceptions to this rule are Staphylococci, Streptococci, Lactococci, Lactobacilli, etc. which contain their own A domain as a C-terminal fusion. This family is closely related to the trehalose transporting PTS IIBC enzymes and the B and C domains of each are described by subfamily-domain level TIGRFAMs models (TIGR00826 and TIGR00852, respectively).

Phosphotransferase system, EIIC; The bacterial phosphoenolpyruvate: sugar phosphotransferase system (PTS) is a multi-protein system involved in the regulation of a variety of metabolic and transcriptional processes. The sugar-specific permease of the PTS consists of three domains (IIA, IIB and IIC). The IIC domain catalyzes the transfer of a phosphoryl group from IIB to the sugar substrate.

PTS system, beta-glucoside-specific IIABC component; This model represents a family of PTS enzyme II proteins in which all three domains are found in the same polypeptide chain and which appear to have a broad specificity for beta-glucosides including salicin (beta-D-glucose-1-salicylate) and arbutin (Hydroquinone-O-beta-D-glucopyranoside). These are distinct from the closely related sucrose-specific and trehalose-specific PTS transporters.

PTS system, maltose and glucose-specific subfamily, IIC component; The PTS Glucose-Glucoside (Glc) Family (TC 4.A.1) Bacterial PTS transporters transport and concomitantly phosphorylate their sugar substrates, and typically consist of multiple subunits or protein domains. The Glc family includes permeases specific for glucose, N-acetylglucosamine and a large variety of a- and b-glucosides. However, not all b-glucoside PTS permeases are in this class, as the cellobiose (Cel) b-glucoside PTS permease is in the Lac family (TC #4.A.3). These permeases show limited sequence similarity with members of the Fru family (TC #4.A.2). Several of the E. coli PTS permeases in the Glc family lack their own IIA domains and instead use the glucose IIA protein (IIAglc or Crr). Most of these permeases have the B and C domains linked together in a single polypeptide chain, and a cysteyl residue in the IIB domain is phosphorylated by direct phosphoryl transfer from IIAglc(his~P). Those permeases which lack a IIA domain include the maltose (Mal), arbutin-salicin-cellobiose (ASC), trehalose (Tre), putative glucoside (Glv) and sucrose (Scr) permeases of E. coli . Most, but not all Scr permeases of other bacteria also lack a IIA domain. This model is specific for the IIC domain of the Glc family PTS transporters.

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
