Phosphoglucomutase (PGM) and UDP-glucose pyrophosphorylase (UGPase) from Gluconacetobacter xylinus.

This part contains two enzymes (2277bp), which is a polycistron in original organism. One of them is phosphoglucomutase (PGM), it can isomerize the glucose-6-phosphate (G-6-P) to glucose-1-phosphate (G-1-P), which is the second reaction for bacterial cellulose production from glucose. Another enzyme is UDP-glucose pyrophosphorylase (UGPase), it can catalyze the glucose-1-phosphate (G-1-P) to react with UTP, forming uridine-5’-phosphate-α-D-glucose (UDPG), which is the third reaction for Bacterial cellulose production from glucose.

These two enzymes were also amplified using PCR method, and inserted into the vector pSB1C3. Fig.1 shows the identification result.
