protein-mosaic-q

Python library for computing the mosaic Q and Q_alt structural descriptors, which quantify the degree of spatial clustering of amino acids by chemical type (acidic, basic, polar, hydrophobic, and also special for Q_alt) in protein three-dimensional structures. Operates on PDB and mmCIF files via Biopython. Associated with the Proteins Mosaic Q Project, a citizen-science initiative gathering evidence for a conserved structural clustering pattern across proteins.
