BsubCyc Overview

BsubCyc is a model-organism database for the bacterium Bacillus subtilis 168. The database was originally based on the genome sequence and annotation published in 2009 [Barbe09], and was updated to reflect changes released in [Borriss18] and [Bremer23]. BsubCyc data content is described here. Gene function annotations are updated periodically based on new literature.

BsubCyc is also part of the larger BioCyc collection of thousands of Pathway/Genome Databases for sequenced genomes, including more than 60 B. subtilis strains. Click the "Change Current Database" button above to explore the available databases.

Tutorial #1: Introduction to BioCyc
These six sequential segments, giving you a guided tour of the BioCyc collection in concise bites. To download or view, just click on one of the links following each segment's name.
Tutorial #2: Introduction to SmartTables
The following Tutorial will guide you through SmartTables, which enable you to create, upload, share, and analyze sets of genes, metabolites, pathways, and sequence sites. The Tutorial is broken up into parts, ranging from basic operations to more advanced uses such as gene expression analysis and metabolomics. To download or view, click one of the links below.
Tutorial #3: Zoomable Metabolic Map, Comparative Tools, Regulatory Network
This tutorial introduces users to many of the advanced tools available on the BioCyc.org website for navigating cellular networks, analyzing large-scale datasets, and comparing organisms.
Tutorial #4: Omics Data Analysis
This tutorial will show you how to use BioCyc's tools for omics data analysis, including the cellular omics viewer, the omics dashboard, and other tools.
Tutorial #5: Pathway Collages
Pathway collages are multi-pathway diagrams that you can customize by, for example, overlaying omics data, altering the relative positions of pathways, and modifying connections among pathways. Learn how to generate, customize and export high-quality pathway-collage diagrams showing collections of user-specified pathways.
Tutorial #6: Creating a Pathway/Genome Database
Tutorial #7: Using the Structured Advanced Query Page
An introduction to the Structured Advanced Query Page, which allows complex queries and queries across one or more databases in the BioCyc collection. You'll learn about:The basic steps of setting up an advanced query; Four examples of increasingly complex queries, including how to query across multiple databases; Where to learn more about the structure of BioCyc databases.
