The AlphaFoldDB Structure Extractor is an open-access web server and API toolkit designed to facilitate the bulk download of predicted protein structures from the AlphaFold Database using well-known accession numbers. Addressing the current limitations in extracting structures beyond a restricted list of model organisms and a threshold number, this tool accepts diverse input identifiers, such as NCBI Taxonomy ID, RefSeq accessions, locus tags, and UniProt or AlphaFold accessions and maps them to UniProt and AlphaFold IDs for structure retrieval. Users can download structure files in PDB, mmCIF, bCIF, or PAE JSON formats. The tool also generates an accompanying ID mapping file to trace input identifiers back to standard accession numbers and reports unmapped IDs separately. An API methodology is also provided for programmatic access, enabling integration into bioinformatics pipelines. AlphaFoldDB Structure Extractor streamlines the structure procurement process from AlphaFold database, empowering researchers in structural and functional genomics with minimal computational expertise. 

novelBGC is an installation-free, browser-based platform for quantitative prioritization of biosynthetic gene clusters (BGCs). It addresses the growing prediction–validation gap in genome mining by integrating multi-source genomic features into a unified RS/N scoring framework that combines MIBiG similarity, gene cluster family (GCF) distance, AMR proximity, and contig-edge quality. By replacing complex, multi-tool command-line workflows with an intuitive web interface and dynamic visualizations, novelBGC enables experimental researchers to rapidly identify and prioritize genuinely novel biosynthetic loci for downstream validation. 

Origenomi webserver is a browser-based tool designed to improve the accuracy and standardization of circular bacterial genome assemblies. Many assembled bacterial genomes retain redundant sequence at their 5′ and 3′ ends, leading to erroneous gene predictions and inflated copy numbers near contig boundaries. Compounding this issue, the lack of a universally accepted convention for defining the genomic start point hampers comparative and synteny analyses. Origenomi addresses both challenges in a unified framework. It first identifies and removes redundant terminal sequences to generate a truly circular, non-redundant genome. The tool then predicts high-confidence OriC and dnaA loci using sequence similarity searches and evaluates candidate pairs with a biologically informed scoring scheme. The genome is finally reoriented to start at the most plausible OriC–dnaA locus, yielding a standardized assembly optimized for downstream genomic analyses. 

VARiantIS is a user-friendly web interface designed to calculate and visualize transitions and transversions in nucleotide sequences. It enables researchers to upload DNA sequence data, compute substitution statistics, and generate intuitive graphical representations for comparative genomics or molecular evolution studies. Developed for accessibility and precision, Variantis simplifies mutation pattern analysis without requiring advanced programming skills, supporting both educational and research applications.
