Abstract
To characterize the molecular properties of CGTase from alkalophilic Bacillus sp. E1 (BCGTE1), a genomic clone for a CGTase was isolated. Expression of recombinant BCGTE1 in E. coli was analyzed by immunoblotting. It showed that the nascent recombinant BCGTE1 expressed was 87 kDa but it was processed into the mature enzyme of 81 kDa. With the process it was secreted predominantly into the culture medium via periplasmic space. This feature is different from other Bacillus CGTases expressed in E. coli, which were present mostly in the periplasmic space.
