== Publication Abstract from PubMed ==

The hemolymph of the fifth instar larvae of the silkworm Bombyx mori contains a group of homologous proteins with a molecular weight of approximately 30kDa, termed B. mori low molecular weight lipoproteins (Bmlps), which account for about 5% of the total plasma proteins. These so-called "30K proteins" have been reported to be involved in the innate immune response and transportation of lipid and/or sugar. To elucidate their molecular functions, we determined the crystal structure of a 30K protein, Bmlp7, at 1.91A. It has two distinct domains: an all-alpha N-terminal domain (NTD) and an all-beta C-terminal domain (CTD) of the beta-trefoil fold. Comparative structural analysis indicates that Bmlp7 represents a new family, adding to the 14 families currently identified, of the beta-trefoil superfamily. Structural comparison and simulation suggest that the NTD has a putative lipid-binding cavity, whereas the CTD has a potential sugar-binding site. However, we were unable to detect the binding of either lipid or sugar. Therefore, further investigations are needed to characterize the molecular function of this protein.
