Sequence-based predictions HEXA

Prediction of disordered regions

• Disopred

Disopred predicts two disordered regions in our protein. The first region is at the beginning of the protein (first two residues) and the second region is at the end (last three regions). This prediction is probably wrong, because it is normal, that the electrons from the first and the last amino acids lack in the electron density map. So, our protein Hexosamidase A has no disordered regions.

Result of the Disopred prediction. * shows that this amino acid belongs to a disordered regions, whereas . signs for a non-disordered region.

• POODLE

We decided to test several POODLE variants and to compare the results.

POODLE-I

POODLE-I predicted five disordered regions:

start position	end position	length
1	2	2
14	19	6
83	89	7
105	109	5
527	529	3

POODLE-L

POODLE-L found no disordered regions. Therefore, there is no disordered region with a length more than 40aa in our protein.

POODLE-S (High B-factor residues)

TODO

POODLE-S predicted five disordered regions:

start position	end position	length
0	2	2
13	19	7
83	88	6
105	109	5
526	529	4

POODLE-S (missing residues)

POODLE-S (missing residues) predicts regions as disordered, if there is a amino acid in the sequence record, but not on the electron density map.

Poodle-S found 6 disordered regions.

start position	end position	length
17	18	2
53	61	9
78	109	33
153	153	1
280	280	1
345	345	1
