Protein

N-acetyl-D-glucosamine kinase

Gene
nagK, ycfX, b1119, JW1105
Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Catalyzes the phosphorylation of N-acetyl-D-glucosamine (GlcNAc) derived from cell-wall degradation, yielding GlcNAc-6-P. Has also low level glucokinase activity in vitro.2 Publications

Catalytic activityi

ATP + N-acetyl-D-glucosamine = ADP + N-acetyl-D-glucosamine 6-phosphate.1 Publication

Enzyme regulationi

Strongly inhibited by ADP.1 Publication

Kineticsi

  1. KM=342 µM for GlcNAc (at 37 degrees Celsius and pH 7.5)2 Publications
  2. KM=896 µM for ATP (at 37 degrees Celsius and pH 7.5)
  3. KM=37 mM for glucose (at 37 degrees Celsius and pH 7.5)
  4. KM=3.4 mM for ATP (at 25 degrees Celsius and pH 7.6)
  5. KM=3.8 mM for glucose (at 25 degrees Celsius and pH 7.6)

Vmax=118 µmol/min/mg enzyme with GlcNAc as substrate (at 37 degrees Celsius and pH 7.5)

Vmax=24 µmol/min/mg enzyme with glucose as substrate (at 37 degrees Celsius and pH 7.5)

pH dependencei

Active from pH 6.5 to 10.
