Hydrolysis of tri- and monoacylglycerol by lipoprotein lipase: evidence for a common active site.

abstract：:Oligothymidylates covalently linked to iron-porphyrins were synthesized to target the nuclease activity of Fe-porphyrin to complementary polynucleotides. In the presence of oxygen and a reducing agent, oligo(dT)7 bearing the reactive group attached to the 3'-phosphate was shown to be active in the cleavage of poly(dA)...
