Rack mechanism

The idea that certain bonds of the substrate are distorted upon binding to the enzyme has been suggested by several workers. This so-called rack mechanism assumes that the substrate fits loosely into the active site, but the bonds that are formed between the enzyme and the substrate are so strong that a susceptible bond within the substrate, is distorted producing the activated transition state (Fig. 4-5). In this mechanism, a portion of the... 

The active site structure of plastocyanin became an archetypal example of the entatic state . The term entatic state was originally coined by Vallee and Williams [34] and brought together a number of ideas including the earlier rack mechanism of Malmstrom [47]. 

Computerised flat weft knitting is the most versatile technology in 3D knitting. The key elements that are essential to the development of 3D knitted textiles include the needle, needle bed, racking mechanism, carriage and cams, yam carriers, take-down...
