Message definition (Enzyme)
[[File:Hexokinase induced fit.svg|alt=Hexokinase displayed as an opaque surface with a pronounced open binding cleft next to unbound substrate (top) and the same enzyme with more closed cleft that surrounds the bound substrate (bottom)|thumb|400px|Enzyme changes shape by induced fit upon substrate binding to form enzyme-substrate complex. [[Hexokinase]] has a large induced fit motion that closes over the substrates [[adenosine triphosphate]] and [[xylose]]. Binding sites in blue, substrates in black and [[magnesium|Mg<sup>2+</sup>]] cofactor in yellow. ({{PDB|2E2N}}, {{PDB2|2E2Q}})]]
ヘキソキナーゼは、未結合の基質(上)と、結合した基質(下)を取り囲む、より閉じたクレフト(裂け目)を持つ、顕著に開いた結合クレフトを持つ不透明な表面として表示される。
酵素は基質と結合すると誘導嵌合によって形を変え、酵素-基質複合体を形成する。ヘキソキナーゼは基質であるアデノシン三リン酸キシロースの上で閉じる大きな誘導嵌合運動を持っている。青が結合部位、黒が基質、黄色が|Mg2+補酵素である。(PDB: 2E2N​, 2E2Q​)
