Preparation

1. Choose a structure to work with

In the former tasks, we worked with the reference structure 1OGS, because it has no gaps - but an offset of 39 residues at the N terminus, as all structures for our protein P04062 referenced in [| UniProt] - and has a pretty low resolution of 2.0 Å. However, there are four other structures with a lower resolution (all resolved using the X-ray method). We compare 1OGS and those four structures for the resolution, coverage and gaps, R-factor, R-free and pH-value at which the structure was resolved in the following table.

PDB-ID Resolution (Å) Chain Positions Gaps R-factor R-free pH Temperature (Kelvin)
1OGS 2.0 A-/B 40-536 no 0.195(obs.) 0.230 4.60 100.0
PDB-ID Resolution (Å) Chain Positions Gaps R-factor R-free pH
PDB-ID Resolution (Å) Chain Positions Gaps R-factor R-free pH
PDB-ID Resolution (Å) Chain Positions Gaps R-factor R-free pH
PDB-ID Resolution (Å) Chain Positions Gaps R-factor R-free pH

2. Visualise the mutations you want to work with

3. Create mutated structures
