# RCSB Saguaro ## Overview The RCSB Saguaro widget is a dynamic and open-source tool tailored to showcase protein features seamlessly on the RCSB Web Site. Leveraging the robust foundation of the RCSB Saguaro 1D Feature Viewer, this widget amalgamates protein annotations from the 1D Coordinate Server and the primary RCSB Data API, culminating in meticulously curated Protein Feature Summaries. Offering flexibility and interactivity, the widget empowers users with access to RCSB Saguaro methods, enabling effortless customization and augmentation of displayed data to suit diverse research needs with unparalleled ease and precision. ## Use Cases * Show protein sequences and annotations. ## Settings The MolStar requires PDB ID to get started. Click the Edit button to select the PDB column * **PDB Column**: Select the column of PDB. ## Interface The RCSB Saguaro widget interface represents a novel library meticulously crafted to exhibit sequence positional features through a web browser client. This development stems from the imperative need to furnish a suite of contemporary, high-performance tools adept at showcasing both structural and biological features. It seamlessly integrates data from various sequence references, navigating the complexities of one-to-many relationships and alignments replete with gaps, thereby offering a comprehensive and unified perspective essential for advanced research endeavors. ## References When using rcsb-saguaro, please cite: *Joan Segura, Yana Rose, John Westbrook, Stephen K Burley, Jose M Duarte.
