Draft entry and computer readable copy of sequence [Gene 28, 263-270 (1984)] kindly provided by A.Horii (14-MAR-1988). [Gene 28, 263-270 (1984)] also sequenced the salivary alpha-amylase mRNA. Comparison of the two alpha-amylase nucleotide sequences reveals 96% homology in the coding region. Comparison of the sequences of human alpha-amylase cDNAs with those for mouse suggest the possibility of gene conversion between the two genes of alpha-amylase.
