摘要

In this study, odorant binding proteins (OBPs) and chemosensory protein (CSP), which are associated with the sensitivity of Grapholita molesta, were comprehensively analysed using bioinformatics. The full-length cDNAs of GmolOBP1, GmolOBP2, and Gmo1CSP were downloaded and their open reading frames (ORFs) were analysed. Their physicochemical properties were determined and their structures and functions were predicted. Additionally, a phylogenetic tree was constructed to investigate the evolutionary relationships among GmolOBP1, GmolOBP2, Gmo1CSP, and 14 other insect proteins. GmolOBP1, Gmo1OBP2 and GmoICSP were composed of 164, 161, and 127 amino acids. GmolOBP1 and GmolOBP2 contained 7 and 6 cysteine residues forming 3 disulphide bonds. The trans membrane, hydrophobic, and signal peptide regions overlapped in GmoIOBP1 and Gmo1CSP and were located in the extracellular environment. Gmo1CSP showed more coiled coils and a smaller cavity in the three-dimensional structure than GmolOBP1 and GmolOBP2. In the phylogenetic tree, GmolOBP1, GmolOBP2, and GmoICSP were in different clusters or sub-clusters. In conclusion, GmolOBP1 and GmolOBP2 shared some common properties with other OBPs. Additionally, GmolOBP1, GmolOBP2, and GmoICSP may have evolved independently. (C) 2016 Elsevier Ltd. All rights reserved.
