Adenylate Kinase (PDB ID #: 1ake)

adenylate kinase bound to non-hydrolyzable substrate analogue

Introduction

Adenylate Kinase is a good little protein.


Physical Properties

Adenylate kinase is caged with water molecules.

I can add headings

This is the AK scene.

Structure

The secondary structure of adenylate kinase shows alpha helices (cyan) and beta sheets (green) surrounding the non-hydrolysable substrate analogue (orange). A network of hydrogen bonds hold the secondary structural elements together. You can see the regular hydrogen bonding pattern in the alpha helices.

Adenylate kinase has a hydrophilic exterior, and a hydrophobic core, with additional hydrophilic residues on the interior contacting the ligand.

Active Site and Mechanism

residues within 3 angstroms of the ligand are involved in binding the ligand or stabilizing the active site.

adenylate kinase's active site is highlighted in dark blue.

together you can see that the active site is only a fraction of the molecules involved in binding the ligand.
