2 transport binding proteins,
3 glycolytic
4) hydrolytic
nota​

Answer 1

Answer:

We have determined and refined the X-ray crystal structures of six periplasmic binding proteins that serve as initial receptors for the osmotic-shock sensitive, active transport of L-arabinose, D-galactose/D-glucose, maltose, sulphate, leucine/isoleucine/valine and leucine. The tertiary structures and atomic interactions between proteins and ligands show common features that are important for understanding the function of the binding proteins. All six structures are ellipsoidal, consisting of two similar, globular domains.
