Catalytic Site Identification

Catalytic Site Identification identifies structural matches for catalytic sites within Protein Data Bank (PDB) protein structures to enable hypothesis generation of enzymatic function.

Key Features:

• Rapid Identification: Identifies structural matches in under one minute using pre-computed data.
• User-Specified Searches: Accepts a specified catalytic site or a submitted protein structure to search against the PDB or a curated library of known catalytic sites.
• Pre-Calculated Database: Maintains a pre-calculated database of matches between all PDB proteins and known catalytic sites to accelerate retrieval of results.
• Hypothesized Enzymatic Annotations: Enables derivation of novel enzymatic function annotations from structural match data.
• Visualization of Matches and Putative Binding Sites: Provides visualization of structural matches and putative binding sites for detailed examination.
• Structural Alignment Precision: Applies structural alignment techniques to ensure high precision in identifying potential matches.

Scientific Applications:

• Enzyme Function Annotation: Supports hypothesis generation for enzymatic activities of uncharacterized proteins based on structural matches to known catalytic sites.
• Protein Engineering: Informs design and modification of proteins by identifying conserved catalytic motifs and structural contexts.
• Experimental Validation Guidance: Guides selection of candidate sites and proteins for biochemical and mutational validation experiments.
• Drug Discovery: Assists in characterizing enzyme active sites relevant to target identification and inhibitor design.
• Synthetic Biology: Aids in designing enzymes with desired activities by mapping structural features of catalytic sites.

Methodology:

Employs advanced computational algorithms to compare user-specified catalytic sites or submitted protein structures against a comprehensive library of known catalytic sites using structural alignment techniques and a pre-calculated database of matches between PDB proteins and known catalytic sites.
