Cloning, characterization, and expression analysis of the CHITINASE gene family in Helice tientsinensis

ABSTRACT: Chitinase is a kind of glycoside hydrolase which is widely distributed in nature and encoded by multiple genes to catalyze the decomposition of chitin, which plays an important role in the molting and pathogen defense of crustaceans. However, the research on chitinase in crustaceans is mainly focused on a few species with economic value. In this study, full-length cDNA sequences of the HtCHT1, HtCHT3 and HtCHT4 genes were cloned from the mudflat crab Helice tientsinensis by RACE, and the sequences were analyzed. The results showed that the full-length 2,229 bp of HtCHT1 gene encoded 627 amino acids, while the full-length 2,191 bp of HtCHT3 gene produced 489 amino acids, and the full-length 3,312 bp of HtCHT4 gene encoded 664 amino acids. Bioinformatics analysis showed that all the obtained
