The complex of retinol with its carrier protein, retinol-binding protein (RBP) has been crystallized and its three-dimensional structure determined using X-ray crystallography. Its most striking feature is an eight-stranded up-and-down beta barrel core that completely encapsulates the retinol molecule. The retinol molecule lies along the axis of the barrel with the beta-ionone ring innermost and the tip of the isoprene tail close to the surface.
视黄醇与其载体蛋白视黄醇结合蛋白(RBP)的复合物已被结晶,并利用X射线晶体学确定了其三维结构。其最显著的特征是一个由八条链组成的上下β桶状核心,它完全包裹着视黄醇分子。视黄醇分子沿着桶的轴排列,β-紫罗兰酮环在最里面,异戊二烯尾巴的末端靠近表面。
