K. Tsuchida et al., PURIFICATION AND PROPERTIES OF A LIPID TRANSFER PARTICLE FROM BOMBYX-MORI - COMPARISON TO THE LIPID TRANSFER PARTICLE FROM MANDUCA-SEXTA, Biochimica et biophysica acta. Protein structure and molecular enzymology, 1337(1), 1997, pp. 57-65
A lipid transfer particle (LTP) was purified from the hemolymph of the
silkworm Bombyx mori. Like other insect LTPs, the B. mori LTP is a ve
ry high density lipoprotein containing 21% lipid and three apoproteins
of mass approximate to 350 kDa, approximate to 85 kDa, and approximat
e to 60 kDa. B. mori LTP catalyzes the exchange of lipids between diff
erent density class lipoproteins found in adult hemolymph and between
adult lipoproteins and vitellogenin. However, in no case was net lipid
transfer observed. Manduca sexta LTP also catalyzed exchange of lipid
s, but not net transfer of lipids, between different density class lip
oproteins found in adult hemolymph.
