Abstract
Purified trehalose synthase from Thermus caldophilus GK24 produced 18-86% trehalose from 10 mM-1 M maltose. The enzyme also catalyzed the conversion of α,α-trehalose into maltose but did not act on other disaccharides. The yield of trehalose from maltose by this enzyme increased 30% more at 40°C than at 80°C and was independent of the substrate concentration. The maximum yield of α,α-trehalose from 10 mM maltose reached 86% at 40°C. In addition, α,β-trehalose was also formed from maltose or α,α-trehalose at 3.5% yield at 80°C.
