Sequence homology between a beta-galactosidase and some beta-glucosidases
1Centre de Recherches sur les Macromolécules Végétales, C.N.R.S., Grenoble, France.
Abstract:
A significant sequence homology was found between a thermostable beta-galactosidase from Sulfolobus solfataricus and two beta-glucosidases, respectively, from Caldocellum saccharolyticum and from Agrobacterium sp. These glycosidases appear to form a new protein family, since no homology could be detected with established beta-galactosidase or beta-glucosidase families.
