8.A.7.1.2









Enzyme I of the PTS (Araki et al., 2011)

Bacteria
Actinomycetota
Enzyme I of Rhodococcus jostii (Q0S1M9)
8.A.7.1.3









Phosphoenolpyruvate: protein phosphotransferase, PTS Enzyme I (based on homology)

Archaea
Euryarchaeota
Enzyme I of Haloterrigena turkmenica (D2RXA5)
8.A.7.1.4









Enzyme I, PtsI (functions with 4.A.2.1.15; Pickl et al., 2012)

Archaea
Euryarchaeota
Enzyme I of Haloferax volcanii (D4GYE2)
8.A.7.1.5









Enzyme I of 591 aas.  Enzyme I transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (HPr).  This protein is encoded in the same operon with an HPr (TC# 8.A.8.1.5) and the IIC and IID genes of a mannose-type PTS system (TC# 4.A.6.1.20).

Bacteria
Calditrichota
Enzyme I of Caldithrix abyssi
8.A.7.1.6









Enzyme I of an archaeal mannose (Man)-type PTS; 566 aas.

Archaea
Thermoproteota
Enzyme I of Thermofilum pendens
