Figure 4.

Properties of archaeal surface-layer proteins. Shown are calculated values of the net charge per residue (a) and standard molal Gibbs energy of formation from the elements (b) at 25°C and 1 bar for surface-layer proteins from archaeal species listed in Table 1. The computed charges per residue of CSG_METFE and CSG_METSC are indistinguishable from one another in (a).
