摘要：
Two secreted alkaline phosphatase proteins were purified from cultures of Bacillus subtilis JH646MS. The two proteins showed slight differences in subunit molecular weight, substrate specificity, and charge characteristics. A total of 62% of the first 22 amino-terminal amino acids were identical. Both sequences showed conservation of structural features identified in Escherichia coli and human alkaline phosphatases. One alkaline phosphatase was a monomer and the other was a dimer. Southern analysis of genomic DNA with degenerative oligomers based on the amino acid sequences suggest that there are two structural genes for alkaline phosphatase in the genome of B. subtilis.
