ENZYME entry: EC 2.5.1.98

Accepted Name
Rhizobium leguminosarum exopolysaccharide glucosyl ketal-pyruvate- transferase.
Reaction catalysed
Phosphoenolpyruvate + [D-GlcA-beta-(1->4)-2-O-Ac-D-GlcA-beta-(1->4)-D-Glc-beta-(1->4)-(3-O-CH(3)-CH(2)CH(OH)C(O)-D-Gal-beta-(1->4)-D-Glc-beta-(1->4)-D-Glc-beta-(1->4)-D-Glc-beta-(1->6))-2(or3)-O-Ac-D-Glc-alpha-(1->6)](n) <=> [D-GlcA-beta-(1->4)-2-O-Ac-D-GlcA-beta-(1->4)-D-Glc-beta-(1->4)-(3-O-CH(3)-CH(2)CH(OH)C(O)-D-Gal-beta-(1->3)-4,6-CH(3)(COO(-))C-D-Glc-beta-(1->4)-D-Glc-beta-(1->4)-D-Glc-beta-(1->6))-2(or3)-O-Ac-D-Glc-alpha-(1->6)](n) + phosphate
Comment(s)
The enzyme is responsible for pyruvylation of subterminal glucose in the acidic octasaccharide repeating unit of the exopolysaccharide of Rhizobium leguminosarum (bv. viciae strain VF39) which is necessary to establish nitrogen-fixing symbiosis with Pisum sativum, Vicia faba, and Vicia sativa.
