Abstract/OtherAbstract:
To elucidate the effects of C-terminal domains of LicMB (mature lichenase from Clostridium thermocellum) and terminal residues of LicMB-CD (catalytic domain of LicMB) on the properties of lichenase, a series of truncated genes were constructed and expressed in E. coli. The Thr-Pro box had a positive effect while the dockerin domain had a negative impact on the properties of LicMB. The N-terminal 10-25th and C-terminal 1-9th residues of LicMB-CD were necessary to retain high thermostability while the N-terminal 1-7th and C-terminal 1-3rd residues were not necessary to maintain enzymatic activity.
