Online Cover This week's issue features a Research Article that describes the crystal structure of the α-kinase domain (A-CAT) of Dictyostelium myosin II heavy chain kinase A (MHCK A), a member of the atypical α-kinase family of serine and threonine protein kinases. Details from this structure reveal features that distinguish α-kinases from conventional protein kinases. The image shows the distribution of electrostatic potential on the surface of A-CAT.
