ABSTRACT:
An enzyme, which has a molecular weight of about 57,000-120,000 daltons on SDS-PAGE and a pI of about 3.8-5.1 on isoelectrophoresis using ampholyte, converts maltose into trehalose and vice versa. The enzyme was isolated from microorganisms of the genera Pimelobacter, Pseudomonas and Thermus. By using the enzyme, trehalose is readily formed from a commercially available maltose in an industrial scale and a relatively-low cost. Trehalose and saccharide compositions containing the same, which are preparable with the enzyme, are suitably used in food products, cosmetic compositions and pharmaceutical compositions.
