Characterization of trehalose phosphorylase from Bacillus stearothermophilus SK-1 and nucleotide sequence of the corresponding gene.
Inoue Y., Ishii K., Tomita T., Yatake T., Fukui F.

A bacterial trehalose phosphorylase (TPase; EC 2.4.1.64) was purified from the culture supernatant of Bacillus stearothermophilus SK-1 to apparent homogeneity, and some properties were investigated. Furthermore, a gene from SK-1 responsible for the TPase was cloned by Southern hybridization with a degenerate oligonucleotide probe synthesized on the basis of the N-terminal sequence of the purified enzyme. The Mr of the enzyme was estimated to be 150,000 by gel filtration and 83,000 by SDS-PAGE, so the enzyme is likely to be a homodimer. The enzyme had optimum activity at pH 7.0-8.0 or nearby and the optimum temperature was about 75 degrees C. The deduced amino acid sequence of the SK-1 TPase encodes a theoretical protein with a Mr of 87,950. Alignment of amino acid sequences with a maltose phosphorylase from Lactobacillus brevis the crystal structure and active site of which had been analyzed suggested that these two phosphorylases evolved from a common ancestor. The Escherichia coli cells harboring the plasmid containing the cloned TPase gene had about 100 times the activity of SK-1. << Less
