Trehalose synthase (TreS) catalyzes the reversible inter-conversion of trehalose (glucosyl-a,a-1,1-glucose) and maltose (glucosyl-a1-4-glucose). TreS was purified from the cytosol ofMycobacterium smegmatisto give a single protein band on SDS gels with a molecular mass of68 kDa. However, active enzyme exhibited a molecular mass of 390 kDa by gel filtration suggesting that TreS is a hexa-mer of six identical subunits.
