PD-(D/E)XK Endonuclease Mapping.
A structural connectivity network with arrows indicating Meta-BASIC
connections between PfamA families (colored circles) and PDB90 families
(structural models). Arrows stem from the input query and are colored
black or gray according to the Meta-BASIC score (above or below the confidence
threshold of 12, respectively). PfamA families colored pink represent newly
predicted restriction endonuclease-like domains, while those colored blue
represent previously known predictions. Two PfamA families with structures
released to the PDB after Meta-BASIC analysis are colored orange. Structural
elements of the PDB90 models are colored blue (core α-helices), yellow (core β-strands),
white (insertions) and purple (domain swaps). Invariant aspartic acid, phosphate
ligand and DNA substrate (where present) are shown in stick representation, while
bound ions are shown in CPK.
