IX型胶原是最近发现的一种罕见的软骨蛋白,具有分段的三螺旋结构,含有链间二硫键。其聚合形式和功能尚不清楚。当由胃蛋白酶从牛关节软骨制备时,发现IX型胶原含有高浓度的羟基吡啶鎓交联,类似于II型胶原。荧光光谱法定位的羟基赖氨酰吡啶啉和赖氨酰吡啶啉交联残基专门在高分子量的胶原蛋白部分,从其中回收主要是在一个单一的CNBr衍生肽。结果指出,软骨基质中的IX型胶原蛋白的结构作用,可能作为粘附材料的II型胶原纤维。
Type IX collagen, a recently discovered, unusual protein of cartilage, has a segmented triple-helical structure containing interchain disulfides. Its polymeric form and function are unknown. When prepared by pepsin from bovine articular cartilage, type IX collagen was found to contain a high concentration of hydroxypyridinium cross-links, similar to that in type II collagen. Fluorescence spectroscopy located the hydroxylysyl pyridinoline and lysyl pyridinoline cross-linking residues exclusively in the high-molecular-weight collagen fraction, from which they were recovered predominantly in a single CNBr-derived peptide. The results point to a structural role for type IX collagen in cartilage matrix, possibly as an adhesion material to type II collagen fibrils.
