cDNA clones mapping within the first 2601 bases of the 3' end of the TGEV genome were sequenced completely or in part by the method of Maxam and Gilbert and open reading frames were examined. One reading frame yielding a protein having properties of the matrix (M) protein was identified. It is positioned at the immediate 5' side of the nucleocapsid (N) gene but is separated by an intergenic region of 12 bases. The deduced M protein is comprised of 262 amino acids, has a molecular weight of 29,544, is moderately hydrophobic, and has an amino acid sequence homology of approximately 36% with the mouse hepatitis coronavirus, 37% with the bovine enteric coronavirus, and 28% with the avian infectious bronchitis virus. Judging from an alignment with MHV and IBV proteins, the amino terminus of the TGEV M protein extends 54 amino acids from the virion envelope which compares with 26 for MHV and 21 for IBV.

D003332	Coronaviridae	Spherical RNA viruses, in the order NIDOVIRALES, infecting a wide range of animals including humans. Transmission is by fecal-oral and respiratory routes. Mechanical transmission is also common. There are two genera: CORONAVIRUS and TOROVIRUS.	Bafinivirus,Coronavirinae,Torovirinae,White bream virus,Bafiniviruses,White bream viruses
D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
