The Draft Genome Sequence and Analysis of an Efficiently Chitinolytic Bacterium Chitinibacter sp. Strain GC72.
2020
A novel chitinolytic bacterium Chitinibacter sp. GC72, which produces an enzyme capable of efficiently converting chitin only into N-acetyl-D-glucosamine (GlcNAc), was successfully sequenced and analyzed. The assembled draft genome of strain GC72 is 3,455,373 bp, containing 3346 encoded protein sequences with G + C content of 53.90%. Among these annotated genes, 17 chitinolytic enzymes including 12 glycoside hydrolase family 18 chitinases, three family 19 chitinases, one family 20 β-hexosaminidase, and one auxiliary activity family 10 lytic polysaccharide monooxygenase, were found to be essential in the production of GlcNAc from chitin. The genomic information of strain GC72 provides a reference genome for Chitinibacter bacteria and abundant novel chitinolytic enzyme resources, and allows researchers to explore potential applications in GlcNAc enzymatic production.
