Short Introduction
This week's task builds on the data gathered last week. We blindly choose 5 disease causing and 5 harmless SNPs and will try to predict their effect from the sequence change alone. You may find a detailed task description at the usual place and consult our task journal.
Our dataset
we propose the following dataset:
- GLU76GLY
- SER87ARG
- GLN172HIS
- ARG158GLN
- ARG243GLN
- LEU255SER
- MET276VAL
- ALA322GLY
- GLY337VAL
- ARG408TRP
You could check them, if you like.. I put them together 5 minutes ago and already forgot, which are which. ;-)
Investigated SNPS
GLU76GLY
From neg. charged, polar, strongly hydrophilic, medium sized to neutral, non-polar, non-hydrophilic, small.

SER87ARG
From neutral, polar, slightly hydrophilic to pos. charged, polar, strongly hydrophilic.
ARG158GLN
From pos. charged, polar, strongly hydrophilic to neutral, polar, strongly hydrophilic.
Close-up of the mutated glutamine at residue 158 in PheOH. The best fitting rotamer was chosen to minimize severe or smaller collisions (red to green discs) with neighbouring residues. This rotamer appears in 1.7% of mutations according to the PyMol rotamer database.
Mutated glutamine at residue 158 in PheOH. The residue is located in a helix region and is statistically less likely in this type of structure than the original arginine.
GLN172HIS
From neutral, polar, strongly hydrophilic to neutral, polar, strongly hydrophilic, ring-structure
Close-up of the mutated histidine at residue 172 in PheOH. The best fitting rotamer was chosen to minimize severe or smaller collisions (red to green discs) with neighbouring residues. This rotamer appears in 18.9% of mutations according to the PyMol rotamer database.
Mutated histidine at residue 172 in PheOH. The residue is located in a coil region.
ARG243GLN
From pos. charged, polar, strongly hydrophilic to neutral, polar, strongly hydrophilic.
Close-up of the mutated histidine at residue 243 in PheOH. The best fitting rotamer was chosen to minimize severe or smaller collisions (red to green discs) with neighbouring residues. This rotamer appears in 17.3% of mutations according to the PyMol rotamer database.
Mutated glutamine at residue 243 in PheOH. The residue is located in a sheet region.
LEU255SER
From neutral, non polar, strongly hydrophobic to neutral, polar, slightly hydrophilic.
Close-up of the mutated serine at residue 255 in PheOH. The best fitting rotamer was chosen to minimize severe or smaller collisions (red to green discs) with neighbouring residues. This rotamer appears in 42.9% of mutations according to the PyMol rotamer database.
