Description

This enzyme catalyses the following chemical reaction: ATP + N-acetyl-D-hexosamine ADP + N-acetyl-alpha-D-hexosamine 1-phosphate. This enzyme is involved in the lacto-N-biose I/galacto-N-biose degradation pathway in the probiotic bacterium Bifidobacterium longum.

Unit Definition

One unit is defined as the amount of enzyme that catalyzes the formation of1 μmol of GlcNAc-1-P from GlcNAc and ATP per minute at 37 °C.
