Definition of crr

• Curated sequence CH_088352: glucose-specific phosphotransferase enzyme IIA component; EC 2.7.1.-. PTS system glucose-specific EIIA component; EIIA-Glc; EIII-Glc; Glucose-specific phosphotransferase enzyme IIA component. Glucose-specific phosphotransferase enzyme IIA component PTGA aka CRR aka GSR aka IEX aka TGS aka TRED aka B2417, component of Glucose porter (PtsG; GlcA; Umg) (transports D-glucose and α-methyl-D-glucopyranoside). Enzyme IIA^Glc (EC 2.7.1.199; EC 2.7.1.201; EC 2.7.1.192). Enzyme IIA^Glc (EC 2.7.1.199)
• Curated sequence P0A283: PTS system glucose-specific EIIA component; EIIA-Glc; EIII-Glc; Glucose-specific phosphotransferase enzyme IIA component
• Ignore hits to Q8L3C4 when looking for 'other' hits (IIA aka Crr, component of The N,N' -diacetylchitobiose Enzyme II (Toratani et al., 2008) (>80% identical to the E. coli enzyme (4.A.3.2.1)))
• Comment: Ignore a close homlog in Serratia (TC 4.A.3.2.5 / Q8L3C4) which is reported to be the II-A component for N,N' -diacetylchitobiose (probably shared with other sugars).
