Python + PyMOL • Arbitrary Python code possible within python scripts • PyMOL functionality available by importing PyMOL's modules cmd, cgo, stored etc. • Call pymol interpreter, which acts on PyMOL specific code and propagates the rest to • Similar concept in MODELLER (modeling), Chimera, Yasara, VMD (visualization) - they all have Python bindings
PyMOL: Center of Mass Calculation Command line execution without graphic interface With graphic interface:
Conservation coloring using Consurf-HSSP • Base: Extracted sequences from SwissProt with high similarity to a certain PDB Entry (HSSP) • Sequence Alignment • Goal: Reflect residue variability in each column on the structural template • Consurf-HSSP: database derivative using Maximum-Likelihood calculation to express residue entropy (round to 1-9)
Consurf-HSSP: Flatfile Data collection • POS: The position of the AA in the SEQRES derived sequence. • SEQ: The SEQRES derived sequence in one letter code. • SCORE: The normalized conservation scores. • 3LATOM: The ATOM derived sequence in three letter code, including the AA's positions as they appear in the PDB file and the chain identifier. • COLOR: The color scale representing the conservation scores (9 - conserved, 1 - variable). • MSA DATA: The number of aligned sequences having an amino acid (non-gapped) from the overall number of sequences at each position. • RESIDUE VARIETY: The residues variety at each position of the multiple sequence alignment.
Movie Making • Different Representations • Arbitrary actions using cmd.mdo • Nice effect: Close-up flights over particularly interesting regions Movie control bar
