step in marine sponge cell recognition and adhesion operates via a calcium-dependent proteoglycan− proteoglycan interaction. For the marine sponge Microciona prolifera, one of the carbohydrate epitopes involved in the proteoglycan self-recognition is a sulfated disaccharide [GlcpNAc3S(β1−3)Fucp]. Earlier surface plasmon resonance studies have demonstrated that the proteoglycan self-recognition can be
海洋海绵细胞识别和粘附的第一步是通过钙依赖性蛋白多糖-蛋白多糖相互作用进行的。对于海洋海绵 Microciona prolifera,参与蛋白多糖自我识别的碳水化合物表位之一是硫酸化二糖 [GlcpNAc3S(β1−3)Fucp]。早期的表面等离子体共振研究表明,当通过与牛血清白蛋白结合多价呈现时,可以用合成的 β-D-GlcpNAc-(13)-α-L-Fucp-(1O) 模拟蛋白多糖的自我识别。在这里,直接合成涂有糖苷 β-D-GlcpNAc3S-(13)-α-L-Fucp-(1O)(CH2)3S(CH2)6SH、β-D-GlcpNAc3S-( 13)-β-L-Fucp-(1O)(CH2)3S(CH2)6SH, β-D-GlcpNAc3S-(1O)(CH2)3S(CH2)6SH, α-L-Fucp-(1O)(CH2 )3S(CH2)6SH, β-D-Glcp-NAc3S-(13)-α-L
