Figure 3
Preliminary electron-density maps, contoured at ∼1.0σ, representing (a) a helical section of B.c TssA CTD. The large side chain visible towards the C-terminal end of the helix corresponds to Trp339, and density can also be seen for the nearby Trp347. Phases were obtained from SHELX (Sheldrick, 2008). (b) A helical section of the B.c His6-TssA Nt1 domain. The large side chain visible at the C-terminal end of the helix corresponds to Phe247, and density can also be seen for the side chain of the adjacent Arg246. Phases were obtained from fast_ep and SHELX (Sheldrick, 2008). Images were generated in Coot (Emsley et al., 2010). |
