Figure 4.

Temperature (B) factors for four different crystal structures of the C subunit. (Left) The Cα trace of the five superimposed structures. Tyr-330 also is shown. Only the tail (residues 301–350) and the glycine-rich loop (residues 47–56) are shown. (Right) A ribbon representation of the Cα-trace for four of these structures, colored according to temperature factors. The scale for the colors is also shown. The structures shown are: I (rC:Mn₂ATP:PKI(5–24);red); II (rC:ADP:(P)PKS; purple); III (rC:adenosine:PKI(5–24); yellow);IV (rC:PKS; blue);V: binary complex (rC:PKI(5–24); turquoise).
