Using cell permeabilization, a technique which allows addition of exogenously supplied radiolabeled sugar nucleotides to serve as direct glycosyl donors, oligosaccharide biosynthesis was examined in fibroblasts obtained from normal and cystic fibrosis (CF) subjects. Incubation of logarithmically
In mammals, two active xylosyltransferase isoenzymes (EC 2.4.2.16) exist. Both xylosyltransferases I and II (XT-I and XT-II) catalyze the transfer of xylose from UDP-xylose to select serine residues in the proteoglycan core protein. Altered XT activity in human serum was found to correlate directly
Fibrosis is a serious health problem often leading to accompanying organ failure. During the manifestation of the disease, an accumulation of different extracellular matrix (ECM) molecules, such as proteoglycans, takes place. There is no appropriate therapeutic option available to heal fibrosis to
