Homology structure groups
We decided to choose every 5% one protein:
| > 60% sequence identity | |||
| PDB id | name | similarity | single template |
| 1ht6_A | AMY1, alpha-amylase iso | 95% | |
| 3aj7_A | Oligo-1,6-glucosidase | 90% | |
| 1h4p_A | Glucan 1,3-beta-glucosidase | 85.2% | |
| 3bc9_A | AMYB, alpha amylase, ca | 80.8% | X |
| 2zum_A | 458AA long hypothetical | 75% | |
| 3bmv_A | Cyclomaltodextrin gluca | 70.3% | |
| 2f2h_A | Putative family 31 gluc | 64.8% | |
| 3emz_A | Xylanase, endo-1,4-beta | 61% | |
| > 40% | |||
| 2dep_A | Xylanase B, thermostabl | 54.9% | |
| 3cui_A | EXO-beta-1,4-glucanase; | 49.5% | X |
| 1vhc_A | Putative KHG/KDPG aldol | 45.1% | |
| 2hk0_A | D-psicose 3-epimerase | 40.8% | |
| < 40% | |||
| 2g0w_A | LMO2234 protein; putati | 35.5% | |
| 3q94_A | Fructose-bisphosphate a | 30.0% | |
| 3hn3_A | Beta-G1, beta-glucuroni | 25.1% | |
| 3lut_A | Voltage-gated potassium | 20.1% | X |

Modeller
We used Modeller from the command line. Therefore we followed the instructions, described here https://i12r-studfilesrv.informatik.tu-muenchen.de/wiki/index.php/Task_4:_Homology_based_structure_predictions#Homology_modelling_with_Modeller.
First of all, we created an alignment for each of our three selected sequences. In the next step we used Modeller to model the 3D structure of the protein.
