Molecular cloning and sequence analysis of the rinderpest virus mRNA encoding the hemagglutinin protein.
We cloned the full-length cDNAs corresponding to the mRNA for the hemagglutinin (H) protein of rinderpest virus (RV) and determined the nucleotide sequence of RV-H. The gene of RV-H was composed of 1952 nucleotides and contained a single large open reading frame, which was capable of encoding a protein of 609 amino acids with a molecular weight of 68,330 Da. The nucleotide sequence and predicted amino acid sequence were compared with those of the measles virus (MV)-H. The 5' end of the message (nucleotides 1 to 485) was largely conserved, with a homology of 75.1% of the nucleotides and 78.0% of the predicted amino acids. In the middle portion (nucleotides 486-1310), where the potential glycosylation sites exist, 56.6% of the nucleotides and 49.5% of the amino acids were identical. In the 3' end of the message (nucleotides 1311-1850), 63.3% of the nucleotides and 58.1% of the amino acids were identical. Four potential glycosylation sites were found in RV-H protein and three of them were the same as those of MV-H protein. The positions of 13 cysteine residues of RV-H were absolutely identical to those of MV-H. The hydropathy profile of RV-H protein resembled that of MV-H. One major hydrophobic region long enough to be an anchor in the membrane was located near the N-terminus.[1]References
