Pike protein consists of S1 and S2 subunit. S1 is head and S2 is rod-shape part, intermolecular effort can bind each other. S1 can bind with host cell epimembranal acceptor. S2 can fix integral Spike protein on the cellular membrane and mediate cell-fusion with virus and host cell. There are significant antigen determinant of virus in Spike protein, genic heterogenesis can effect viral pathogenicity. SARS-CoV Spike protein, which has 23 pieces larvaceous glycosylation sit, consists of 1256 amino acid. Its N-terminals and C-terminals is corresponding conservative.

吴奕德91M01：利用真空湿式反应室进行即时就地胶原蛋白固定之研究。

The result of immobilization showed that hydrophile membranes were more advantageous than hydrophobe ones to act as immobilization carrier. Crosslinking organophosphorus hydrolase by glutaraldehyde on polyethersulfone membrane is a simple and practical immobilization method. An appropriate amount of bovine serum albumin and crosslinker is necessary to get a good result of immobilization. In the biodegradation of methyl-parathion through enzyme membrane reactor, the effect of immobilized enzyme amount, flow rate of peristaltic pump, pH of the feed, and the methyl-parathion concentration on biodegradation rate was studied. It was shown that the biodegradation rate increased with immobilized enzyme amount and substrate concentration. Biodegradation rate didn't increase when the folw rate of the peristaltic pump was larger than 7 ml/min.
