Figure 4
Stereoview of a standard OMIT map (Fo - Fc) at 3[sigma] for AMP (a) and tubercidin (b) in the ATP-binding site (molecule A). The average B factor for tubercidin is very high (61.62 Å2) as a result of very loose contacts within the ATP-binding site, leading to less well defined electron density.  [article HTML]
