Functional Characterization of exo- and endo-Arabinosyl Hydrolases and Their Synergistic Actions in Arabinan- Utilization of Bacillus Species

초록

영어

Arabinans are unique hemicellulosic homo-polymers in nature which consists of α -(1,5)-linked main backbone and α-(1,2)- and/or α-(1,3)-linked branches of L-arabinoses. Based on the genomes of Bacillus species, the gene clusters encoding various arabinan-degradaing enzymes such as exo-acting α-L-arabino- furanosidases (AFs) and endo-α-(1,5)-L-arabinanases (ANs). Their functional expression and characterization revealed that these hydrolases possess distinct hydrolytic mode of actions and work synergistically with each other. According to the comparative genomics study, the probable roles of each hydrolase for the efficient arabinan-degradation and utilization in Bacillus species as the model bacterial systems have been proposed in this study.
