Background:Maltose metabolism during leaf starch degradation requires a multidomain glucanotransferase and a complex polysaccharide. Results: A conventional bacterial glucanotransferase rescues an Arabidopsis mutant lacking the multidomain glucanotransferase. Conclusion:Both the plant glucanotransferase-polysaccharide couple and the bacterial enzyme provide a glucosyl buffer in the starch degradation pathway. Significance:New light is shed on the regulation and evolution of maltose metabolism.
