CC   -!- The enzyme is responsible for pyruvylation of subterminal glucose in
CC       the acidic octasaccharide repeating unit of the exopolysaccharide of
CC       Rhizobium leguminosarum (bv. viciae strain VF39) which is necessary
CC       to establish nitrogen-fixing symbiosis with Pisum sativum, Vicia
CC       faba, and Vicia sativa.
