PROTEIN CHARACTERIZATION AND FATTY ACID COMPOSITION OF VHDL SUBFRACTION II OF THE SPIDER POLYBETES PYTHAGORICUS -

[摘要] ABSTRACT: VHDL fraction contains hemocyanin as its major apoprotein and transports most of the circulating lipids in the spider Polybetes pythagoricus (Sparassidae). This work shows that subfraction II (the major VHDL component) is composed of a single protein of 420 kDa under native conditions and three subunits, 67, 105 and 121 kDa under denaturing conditions. Circular dichroism indicated that this subfraction contains 20% -helix, 29% -sheet, 22.7% turns and 29.7% unordered structures. Compari.
