Digestions of bovine skin proteodermatan sulphate with cathepsin C proved that the dermatan sulphate was located on Ser-4 in most of the molecules. A Ser-Gly sequence is essential for xylosylation of the serine residue and sulphated galactosaminoglycan synthesis in different proteoglycans. Variations in adjoining sequences may be significant in relation to the glycosylation process in different tissues.
用组织蛋白酶C消化牛皮蛋白聚糖硫酸皮肤素证明,在大多数分子中,硫酸皮肤素位于丝氨酸-4上。丝氨酸-甘氨酸序列对于丝氨酸残基的木糖基化以及不同蛋白聚糖中硫酸化半乳糖胺聚糖的合成至关重要。相邻序列的变化可能与不同组织中的糖基化过程密切相关。
