Cloning and Expression of the pga Gene of Bacillus megaterium in E. coli.

The pga gene was amplified by PCR from Bacillus megaterium CA4098, cloned into pKK223-3 vector and expressed in E. coli HB101. The pga sequence was also determined. The deduced amino acids sequence was compared with those of PGAs from other bacteria and showed that they were similar, especially the active sites were strongly conserved.
