Enzymes

Protein Details
1. Phosphoenolpyruvate-protein phosphotransferase
General function:
Involved in transferase activity, transferring phosphorus-containing groups
Specific function:
General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. Enzyme I transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (HPr)
Gene Name:
ptsI
Uniprot ID:
P08839
Molecular weight:
63561
Reactions
Phosphoenolpyruvate + protein L-histidine = pyruvate + protein N(pi)-phospho-L-histidine.
Protein Details
2. PTS system maltose- and glucose-specific EIICB component
General function:
Involved in protein-N(PI)-phosphohistidine-sugar phosphotransferase activity
Specific function:
MalX encodes a phosphotransferase system enzyme II that can recognize glucose and maltose as substrates even though these sugars may not represent the natural substrates of the system
Gene Name:
malX
Uniprot ID:
P19642
Molecular weight:
56627
Reactions
Protein EIIB N(pi)-phospho-L-histidine/cysteine + sugar = protein EIIB + sugar phosphate.
Protein Details
3. Glucose-specific phosphotransferase enzyme IIA component
General function:
Involved in sugar:hydrogen symporter activity
Specific function:
The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active -transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in glucose transport
Gene Name:
crr
Uniprot ID:
P69783
Molecular weight:
18251
Reactions
Protein EIIA N(pi)-phospho-L-histidine + protein EIIB = protein EIIA + protein EIIB N(pi)-phospho-L-histidine/cysteine.
Protein Details
4. Phosphocarrier protein HPr
General function:
Involved in sugar:hydrogen symporter activity
Specific function:
General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The phosphoryl group from phosphoenolpyruvate (PEP) is transferred to the phosphoryl carrier protein HPr by enzyme I. Phospho-HPr then transfers it to the permease (enzymes II/III)
Gene Name:
ptsH
Uniprot ID:
P0AA04
Molecular weight:
9119
Reactions
Protein HPr N(pi)-phospho-L-histidine + protein EIIA = protein HPr + protein EIIA N(tau)-phospho-L-histidine.
