2mFo − DFc electron-density maps of PC (a) and proteinase K (b) contoured at 1σ. (a) The two PC subunits (α, blue; β, pink) are shown in cartoon representation. The three chromophores are shown as yellow sticks. A closer view of the chromophore in the black box is shown in the right panel. (b) Proteinase K is shown in a yellow cartoon and stick representation. One of the two Ca atoms is shown as a green sphere. A closer view of the Ca atom is illustrated in the right panel. |
