unsaturated hexa((1-4)-alpha-L-guluronan) the enzyme degrades unsaturated hexaguluronans faster than saturated hexaguluronans, its subsite number appears to be seven Enterobacter cloacae unsaturated triguluronic acid + unsaturated tetraguluronic acid unsaturated trimers are the mayor product ?

unsaturated pentaguluronan also degrades unsaturated hexa- and hepta-guluronans, not unsaturated oligoguluronans with degree of polymerization less than four, cleaves the second glycosidic linkage from the non-reducing end of unsaturated pentaguluronans and heptaguluronans Enterobacter cloacae ?
