Surface plasmon resonance studies using C-terminal truncation forms of the S-layer protein SbsC (recombinant SbsC consisting of amino acids 31 to 270 [rSbsC(31-270)] and rSbsC(31-443)) and the secondary cell wall polymer (SCWP) isolated from Geobacillus stearothermophilus ATCC 12980 confirmed the exclusive responsibility of the N-terminal region comprising amino acids 31 to 270 for SCWP binding. Quantitative analyses indicated binding behavior demonstrating low, medium, and high affinities.
使用嗜热栖热放线菌ATCC 12980的S层蛋白SbsC的C端截短形式(由氨基酸31至270组成的重组SbsC[rSbsC(31 - 270)]和rSbsC(31 - 443))以及从嗜热栖热放线菌中分离出的次生细胞壁聚合物(SCWP)进行的表面等离子体共振研究证实,包含氨基酸31至270的N端区域对SCWP结合具有唯一责任。定量分析表明其结合行为表现出低、中、高亲和力。
