Analysis of xylosyltransferase II binding to the anticoagulant heparin.
The key enzymes in the biosynthetic pathway of glycosaminoglycan production are represented by the human xylosyltransferase I and its isoform II (XylT-I and XylT-II). The glycosaminoglycan heparin interacts with a variety of proteins, thereby regulating their activities, also those of xylosyltransferases. The identification of unknown amino acids responsible for heparin-binding of XylT-II was addressed in this study. Thus, six XylT-II fragments were designed as fusion proteins with MBP and we received soluble and purified MBP/XylT-II from Escherichia coli. Heparin-binding studies showed that all fragments bound with low affinity to heparin. Prolonging of XylT-II fragments did not account for a cooperative effect of multiple heparin-binding motifs and in turn for a stronger heparin-binding. Sequence alignment and surface polarity plot led to the identification of two highly positively charged Cardin-Weintraub motifs with surface accessibility, resulting in combination with short clusters of basic amino acids for strong heparin-binding of native xylosyltransferases.
