Motion in c-Src tyrosine kinase [csrc]

[ jump to morphs ]

Classification Known Domain Motion, Hinge Mechanism [D-h-2]

Structures 1FMK Conformation 1 [ PartsList ] 2SRC Conformation 2

Description Structure of a large fragment of the c-Src tyrosine kinase shows that interactions among domains, stabilized by binding of the phosphorylated tail to the SH2 domain, lock the molecule in a conformation that simultaneously disrupts the kinase active site and sequesters the binding surfaces of the SH2 and SH3 domains. N lobe rotates 9 degress relative to its position in the cAPK Sidechain of Glu310 moves 12 A.

Particular values describing motion Maximum CA displacement (A) = 12 (from lit.) Maximum Rotation (degrees) = 9 (from lit.) Experimental Methods = x (Traditional x-ray) Creation Date = 19970822 Modification Date = 19971212
