Abstract

Chitin deacetylases (CDAs) are one of the least understood components of insect chitin metabolism. The partial deacetylation of chitin polymers appears to be important for the proper formation of higher order chitin structures, such as long fibers and bundles, which contribute to the integrity of the insect exoskeleton and other structures. Some CDAs may also be involved in bacterial defense. Here, we report the manual annotation of four CDA genes from the Asian citrus psyllid, Diaphorina citri, laying the groundwork for future study of these genes.

Highlights

Chitin deacetylases (CDAs) are metalloenzymes that partially deacetylate chitin polymers [1]
CDA activity in insects was first reported in the cabbage looper Trichoplusia ni [2]
Genomic and phylogenetic studies have shown that CDAs are present widely in insects and can be classified into five different groups [5, 6]

Summary

Introduction

Chitin deacetylases (CDAs) are metalloenzymes that partially deacetylate chitin polymers [1]. The exact role of insect CDAs is not well understood, but they may play a role in organization of chitin molecules into higher order structures [7]. We describe the chitin deacetylase gene family in the Asian citrus psyllid, Diaphorina citri (Hemiptera: Liviidae; NCBI:txid121845).
