physiological function | glycosyltransferases of family 1 are capable of transferring sugar moieties from activated sugar donors to a wide range of small lipophilic acceptors leading to an increase in water solubility, improved chemical stability and altered biological activity of the sugar conjugates, in plants, family 1 glycosyltransferases play an important role in metabolic homeostasis, regulation of phytohormone activities and detoxification of xenobiotics such as herbicides and pesticides | Arabidopsis thaliana |
