Although the integrase (IntDOT) of the Bacteroides conjugative transposon CTnDOT has been classified as a member of the tyrosine recombinase family, the reaction it catalyzes appears to differ in some features from reactions catalyzed by other tyrosine recombinases. We tested the ability of IntDOT to cleave and ligate activated attDOT substrates in the presence of mismatches. Unlike other tyros...

Hypersensitivity reactions caused by ant stings are increasingly recognized as an important cause of death by anaphylaxis. Only some species of ants ( e.g. Solenopsis spp., Myrmecia spp., and Pachycondyla spp.) cause allergic reactions. Ant species are identified by evaluating the morphologic structures of worker ants or by molecular techniques. Ant venom contains substances, including acids an...

We describe here the first example of an iterative convergent strategy for the synthesis of dendritically branched polymers involving condensation coupling reactions of AB2 macromonomers. The macromonomers were synthesized by living anionic polymerization, initiated with 3-tertbutyldimethylsiloxy-1-propyllithium and end capped with 1,1-bis(4-tert-butyldimethylsiloxyphenyl) ethylene. Following a...

The gene product, phosphodiesterase 4D (PDE4D) is anchored at the centrosome-Golgi cell region by phosphodiesterase 4D interacting protein (PDE4DIP). PDE4D is a member of a family of phosphohydrolyases. These enzymes are involved in signal transduction and hydrolyze 3' cyclic phosphate bonds in 3’, 5’cGMP and 3’,5’-cAMP to energyze several reactions in the cell. The latter are termed second mes...
