ABSTRACT
We analyzed the glycoprotein gene sequences of a Chinese street rabies virus strain (CGX89-1) and a Chinese human rabies vaccine strain (3aG). The complete glycoprotein gene sequence of each strain has 1575 nucleotides and encodes a polypeptide of 524 amino acids. The overall nucleotide homology of these glycoprotein genes is 84.5%, and the deduced amino acid homology is 89.5%. Twenty-one percent of the base changes result in amino acid substitutions. Comparison of the homologies of the glycoprotein genes showed that the most conserved region is the ectodomain, whereas the most variable regions are the transmembrane and cytoplasmic domains. The overall nucleotide homologies of the 3aG glycoprotein and the CGX89-1 glycoprotein compared with the Pasteur virus glycoprotein are 91.2% and 84.1% respectively. The glycoprotein gene sequences presented here, the first from isolates of Chinese origin, provide insights into the biologically significant regions of this rabies gene.
