Sequencing of p35 gene fromHeliothis armigera polyhedrosis virus and its homologous comparison

Using p35 gene primers of AcNPV, about 1 kb fragment was obtained by PCR from HaNPV DNA and was sequenced thereafter. It has a full reading frame encode 299 amino acids. Sharing identity of 94% in nucleotides and 84% in predict amino-acids with AcNPV, a apoptosis inhibiting gene was found. According to comparison of p35 genes in five kinds of baculovirus, it is found that AcNPV, TnNPV and BmNPV share the most intimate blood relation. HaNPV is near the above three species. LsNPV is little remote from them. This result reconfirmed those we have done with gp37 genes and vp39 genes. It is more accurate to use conserved gene for species division than that of the serological identification. Biography: WANG Ye-fu(1962-), male, Ph D.

Fast docking of drug molecules to their receptor

AEDock based on AutoDock2.4 is developed with annealing evolution algorithm (AEA) in place of simulated annealing algorithm (SA) for supermolecular conformation searching. Because AEA takes advantage of both the genetic algorithm (GA) and the simulated annealing algorithm, the results of AEDock show that AEA can predict the binding conformations of ligands with up to 10 rotatable bonds to a rigid macromolecular target. The case of 1 hvr is only one of six cases where SA in AutoDock 2.4 failed to find an energy less than that of the crystal. It is used here to compare the performance of SA with AEA. The results of comparison show that fewer states are needed in AEA than in SA, but the success rate of AEA is much higher.
