Abstract

Chemosensory Proteins (CSPs) represent a family of conserved proteins found in insects that may be involved in chemosensory functions. BmorCSP1 is expressed mainly in antennae and legs of the silkworm moth Bombyx mori and was cloned from antennal cDNA. Here we report the determination of the structure of Bombyx mori CSP1 (BmorCSP1) by NMR. The overall fold of BmorCSP1 is globular and comprises six α‐helices. These helices span residues 10–14, 17–27, 35–49, 57–72, 75–85, and 92–100. The internal hydrophobic sides of the helices are formed mostly by leucine and isoleucine residues and, therefore, well suited to constitute a binding site for hydrophobic ligands. Arch.

Bombyx mori silk fibroin from the silkworm was found to be soluble in a calcium nitrate-methanol system. Fibroin dissolves in 75% w/v Ca(NO 3 ) 2 /MeOH solution at a temperature of 67ЊC. The viscometric behavior of the fibroin-salt solution was analyzed and the fibroin's secondary structures were de
