Crystal structure of MKP-4C. (a) Ribbon representation of the catalytic domain of MKP-4. Secondary-structural boundaries are α1, 222–228; α2, 268–282; α3, 295–309; α4, 311–323; α5, 331–346; β1, 205–208; β2, 211–214; β3, 232–237; β4, 243–246; β5, 251–255; β6, 285–289. (b) Comparison of Cα traces. The Cα trace of MKP-4C (black) is superimposed on that of MKP-5C (red). Superposition was performed with the program O (Jones et al., 1991) using a criterion of less than 3.8 Å for more than three consecutive Cα atoms. The regions that significantly deviate are labelled on the drawing. PTP, PTP-loop; GA, general acid loop. |
