What is Qmean score?
QMEAN, which stands for Qualitative Model Energy ANalysis, is a composite scoring function describing the major geometrical aspects of protein structures. Five different structural descriptors are used. The local geometry is analyzed by a new kind of torsion angle potential over three consecutive amino acids.
How accurate is SWISS-MODEL?
SWISS-MODEL is a structural bioinformatics web-server dedicated to homology modeling of 3D protein structures. Homology modeling is currently the most accurate method to generate reliable three-dimensional protein structure models and is routinely used in many practical applications.
How do Swiss models work?
SWISS-MODEL provides several levels of user interaction through its World Wide Web interface: in the 'first approach mode' only an amino acid sequence of a protein is submitted to build a 3D model. Template selection, alignment and model building are done completely automated by the server.
What is a good Qmean value?
QMEAN z-scores around zero indicate good agreement between the model structure and experimental structures of similar size. Models of low quality typically have scores of -4.0 or lower. The “thumbs-up” and “thumbs-down” symbols next to the score are used to indicate whether or not the model is of good quality (9).
What is GMQE in SWISS-MODEL?
GMQE (Global Model Quality Estimate) is a quality estimate which combines properties from the target-template alignment and the template structure.
What is the purpose of SWISS-MODEL?
is a fully automated protein structure homology-modelling server, accessible via the Expasy web server, or from the program DeepView (Swiss Pdb-Viewer). The purpose of this server is to make protein modelling accessible to all life science researchers worldwide.
How can I become a SWISS-MODEL?

What is Swiss PDB?
Description. Swiss-PdbViewer (aka DeepView) is an application that provides a user friendly interface allowing to analyze several proteins at the same time. The proteins can be superimposed in order to deduce structural alignments and compare their active sites or any other relevant parts.
How do you reference a SWISS-MODEL?

What is Rmsd in protein structures?
Root mean square deviation (RMSD) is used for measuring the difference between the backbones of a protein from its initial structural conformation to its final position. The stability of the protein relative to its conformation can be determined by the deviations produced during the course of its simulation.
Why is homology Modelling important?
Homology modeling obtains the three dimensional structure of a target protein based on the similarity between template and target sequences and this technique proves to be efficient when it comes to studying membrane proteins that are hard to crystallize like GPCR as it provides a higher degree of understanding of ...
What is homology Modelling in bioinformatics?
Homology modeling, also known as comparative modeling of protein, refers to constructing an atomic-resolution model of the "target" protein from its amino acid sequence and an experimental three-dimensional structure of a related homologous protein (the "template").
SWISS-MODEL: Uses & Applications
SWISS-MODEL [1] is a bioinformatics tool that is widely used for protein structure prediction. In this article, we are going to discuss its uses and applications.
Homology Modeling of α-Glucosidase Enzyme: 3D Structure Prediction
The word “Homology modeling”, means comparative modeling or sometimes it is known as Template-Based Modeling (TBM), which refers to develop a three dimensional model of a...
How to build a homology model using superoxide dismutase
Here, we provide a step-by-step example on how to build a homology model for the Superoxide Dismutase [Cu-Zn] protein from Drosophila melanogaster (SOD, UniprotKB AC: P61851).
How to model the correct oligomeric state of a protein using ornithine carbamoyltransferase
In this example we show how to infer the quaternary structure of Ornithine Carbamoyltransferase from Thermus thermophilus (OTC, UniProtKB AC P96134). OTC is involved in arginine biosynthesis, where it catalyses the formation of citrulline and phosphate from ornithine and carbamoyl phosphate.
How build a model using the DeepView Project Mode
In order to demonstrate how to use DeepView to build oligomeric assemblies, we are going to build a model of the protease of murine leukemia virus based on the PDB file 3S43. (Please keep in mind that this is just an example to illustrate the workflow; presumably, there would be much better templates available.)
How to build a model for a hetero-oligomeric protein using hemoglobin
In this example, we are going to build a model of the hemoglobin from Physeter macrocephalus (Sperm whale). Hemoglobin is the oxygen-carrying protein of red blood cells. It is made up of four protein chains (globulins) connected together to form a heterotetramer.
