Enzymes

Protein Details
1. PTS system mannitol-specific EIICBA component
General function:
Involved in transporter 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 mannitol transport
Gene Name:
mtlA
Uniprot ID:
P00550
Molecular weight:
67972
Reactions
Protein EIIA N(pi)-phospho-L-histidine + protein EIIB = protein EIIA + protein EIIB N(pi)-phospho-L-histidine/cysteine.
Protein EIIB N(pi)-phospho-L-histidine/cysteine + sugar = protein EIIB + sugar phosphate.

2. 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.

3. 6-phospho-beta-glucosidase
General function:
Involved in hydrolase activity, hydrolyzing O-glycosyl compounds
Specific function:
Hydrolyzes a wide variety of P-beta-glucosides including cellobiose-6P, salicin-6P, arbutin-6P, gentiobiose-6P, methyl- beta-glucoside-6P and p-nitrophenyl-beta-D-glucopyranoside-6P. Is also able to hydrolyze phospho-N,N'-diacetylchitobiose
Gene Name:
chbF
Uniprot ID:
P17411
Molecular weight:
50512
Reactions
6-phospho-beta-D-glucosyl-(1,4)-D-glucose + H(2)O = D-glucose + D-glucose 6-phosphate.
Protein Details
4. Chitooligosaccharide deacetylase ChbG
General function:
polysaccharide catabolic process
Specific function:
ChbG is essential for growth on the acetylated chitooligosaccharides chitobiose and chitotriose but is dispensable for growth on cellobiose and chitosan dimer, the deacetylated form of chitobiose. Deacetylation of chitobiose-6-P and chitotriose-6-P is necessary for both the activation of the chb promoter by the regulatory protein ChbR and the hydrolysis of phosphorylated beta-glucosides by the phospho-beta-glucosidase ChbF. Catalyzes the removal of only one acetyl group from chitobiose-6-P to yield monoacetylchitobiose-6-P, the inducer of ChbR and the substrate of ChbF. It can also use chitobiose and chitotriose as substrates.
Gene Name:
chbG
Uniprot ID:
P37794
Molecular weight:
27773
Reactions
2-(acetylamino)-4-O-(2-(acetylamino)-2-deoxy-beta-D-glucopyranosyl)-2-deoxy-beta-D-glucopyranose + H(2)O = 2-(acetylamino)-4-O-(2-amino-2-deoxy-beta-D-glucopyranosyl)-2-deoxy-beta-D-glucopyranose + acetate
