Protein Molecular Surface Calculator

ProMS, the protein molecular surface calculator, is an integrated application that was developed to calculate and visualize molecular surface properties. The software is available to download free of charge for those interested. For access to the source code and documentation, please contact the lab.

The precursor to ProMS was PSPC (Protein Surface Property Calculator, 2003). ProMS development began in 2021 to update the software and provide additional functionality and features (read more below). For more information pertaining to PSPC, read here.

Molecular Surfaces

Molecular surfaces play an integral role in many biological processes. They are involved in protein folding, protein-protein interactions, molecular recognition, molecular docking, signaling, and more. In 1983, Michael Connolly developed an algorithm to generate the geometrical molecular surface of any protein given as in input.

In simple terms, the “Connolly surface” is generated by rolling an imaginary sphere over the 3D structure of the molecule. The output surface is thus a function of the sphere’s radius (also referred to as the probe radius). To this day, Connolly’s algorithm remains the most popular analytical method for mapping protein surfaces.

ProMS Features

For a more detailed summary of ProMS’ features, please reference the user manual.

Surface property calculations
- Computations derived from Connolly’s msRoll and Nicolau’s work on atomic hydrophobicities
- “Under the hood” – complexity and tediousness is hidden by the intuitive GUI
- Multiple output file formats, including a .mov file if visualization is enabled
- A sample of the output in tabular form can be found below

Choice of various input parameters
- PDB ID, probe radius (1.4-20A), pH, hydrophobicity scale
- Computations via Method 1 or Method 2 at either atomic or amino acid resolution

Integration within PyMOL & design of custom visualization modules
- ProMS is an extension of Schrodinger’s PyMOL, an open-source molecular manipulation tool
- Design of custom modules allows for the visualization of Nicolau’s hydrophobicity algorithms for any protein

Batch mode
- Enables the analysis of several proteins / different parameters at the click of a single button

Custom PDB integration
- Supports PDBs that have been modified by the user or that have not yet been published to an online database

ProMS Sample Output

Below is a sample of the properties calculated by ProMS, aggregated into a table. The analyzed proteins correspond to the same proteins chosen for the BAD project. These properties were calculated using Nicolau’s Method 1 and the “Dgwif” hydrophobicity scale. There are four copies of each PDB because the probe radius (1.4A vs 20A) and the resolution (atomic vs amino acid) were changed (see last two columns).

The majority of the output columns are self-explanatory. However, some of the secondary properties, such as density, specific density, and area extent are less intuitive.

Density = total charge or hydrophobicity / total area
Specific density = total charge or hydrophobicity / total charged area or hydrophobic area
Area extent = charged or hydrophobic area / total area
All areas are in units of square Angstroms

Additional Output

In addition to the properties above, ProMS also outputs detailed area calculations and the solvent-excluded volume via Connolly’s msRoll. Furthermore, using the protein’s molecular weight from literature, an atomic volume can also be calculated. Lastly, sphericity, monolayer volume density, and monolayer weight can all be computed from the aforementioned values. The results can be found in the table below.
