The enzymatic synthesis of β1-2 glucans

Incubation of labeled uridine diphosphate glucose with an enzyme preparation from Rhizobium meliloti or Agrobacterium tumefaciens leads to the formation of a glucan which appears to be identical to the β1-2 cyclic glucan described by several workers. This conclusion is based on the molecular size, t...
