After amplying a 2.2kb fragment form the PPV-SC1 RF-DNA,we clone the fragment into pMD 18-T,named pTNSl.The whole sequence which is 1989 bp long was determined by sequencing, including the complete ORF of PPV-SC1 NS1 which encoding 662 amino acids.Alignment of pairs of sequence indicates that there are 98% and 99% similary with other porcine parvovirus strains Kresse and NADL-2, respectively. Multiple sequence alignment discloses that there are a few difference between ppv-scl nsl gene and other ppv nsl gene: A-G at 39nt,T-C at 153nt,A-G at 175nt, A-C at 1117nt, A-C at 1535nt .Alternative codon in ppv-scl nsl have distinctly different frequentfy by codonbias analysis at EMBOSS(http://genopole.toulouse.inra.fr/bioinfo/emboss). Thereis not distinct hydrophobicity and transmenbrane helices in ppv-scl nsl protein. Struction domain anslysis of PPV-SC1 NS1 protein indicate that there are a ATP/GTP-binding site motif A at 398-405,16 Protein kinase C phosphorylation site,21 Casein kinase II phosphorylation site,and 3 cAMP/cGMP-dependent protein kinase phosphorylation site.At the same time ,there is a same motif between ppv-scl nsl and Poxvirus D5 protein-like which may share in the same fuction which is necessary during virion duplication.
