Fig. 2From: Enhanced thermal stability of lichenase from Bacillus subtilis 168 by SpyTag/SpyCatcher-mediated spontaneous cyclization a SDS-PAGE analysis of proteolytic digestion products of cyclized lichenase. Lanes lane M marker; lane 1 purified cyclized lichenase before digestion; lane 2 the corresponding products after digestion. The band with an apparent molecular weight of 48 kDa is the TEV protease. b and c MALDI-TOF mass spectrum of lichenase undergoing cyclization before b and after c TEV cleavageBack to article page
