A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 2.7.11.18

Accepted Name
[Myosin light-chain] kinase.
Alternative Name(s)
[Myosin-light-chain] kinase.
Calcium/calmodulin-dependent myosin light chain kinase.
MLCK.
MLCkase.
Myosin kinase.
Myosin light chain kinase.
Myosin light chain protein kinase.
Myosin light-chain kinase.
Myosin light-chain kinase (phosphorylating).
Smooth-muscle-myosin-light-chain kinase.
Reaction catalysed
ATP + [myosin light-chain] <=> ADP + [myosin light-chain] phosphate
Cofactor(s)
Ca(2+).
Comment(s)
  • Requires calmodulin for activity.
  • The 20 kDa light chain from smooth muscle myosin is phosphorylated more rapidly than any other acceptor, but light chains from other myosins and myosin itself can act as acceptors, more slowly.
  • Formerly EC 2.7.1.117.
