Article Synopsis
  • Legume nodules make a lot of heme, which is important for creating leghemoglobin that helps plants fix nitrogen.
  • Scientists studied a plant called Lotus japonicus to find out how a specific enzyme called LjHO1 helps break down heme and discovered that this enzyme is crucial for keeping the plant healthy and fixing nitrogen.
  • When they mutated (changed) the LjHO1 gene, the plants had fewer green nodules and couldn't fix nitrogen well, showing that LjHO1 is really important for the plant's health and defense against stress.

Background: Compared with steviol glycosides, the taste of glucosylated steviol glycosides is better and more similar to that of sucrose. At present, cyclodextrin glucanotransferase (CGTase) is primarily used to catalyze the conversion of steviol glycosides to glucosylated steviol glycosides, with soluble starch serving as a glycosyl donor. The main disadvantages of enzymatic transglycosylation are the limited number of enzymes available, the low conversion rates that result in low yields, and the lack of selectivity in the degree of glycosylation of the products.
