Abstract

A regular update of genome annotations is a prerequisite step to help maintain the accuracy and relevance of the information they contain. Five years after the first publication of the complete genome sequence of Clostridium difficile strain 630, we manually reannotated each of the coding sequences (CDSs), using a high-level annotation platform. The functions of more than 500 genes annotated previously with putative functions were reannotated based on updated sequence similarities to proteins whose functions have been recently identified by experimental data from the literature. We also modified 222 CDS starts, detected 127 new CDSs and added the enzyme commission numbers, which were not supplied in the original annotation. In addition, an intensive project was undertaken to standardize the names of genes and gene products and thus harmonize as much as possible with the HAMAP project. The reannotation is stored in a relational database that will be available on the MicroScope web-based platform (https://www.genoscope.cns.fr/agc/microscope/mage/viewer.php?S_id=752&wwwpkgdb=a78e3466ad5db29aa8fe49e8812de8a7). The original submission stored in the (International Nucleotide Sequence Database Collaboration) INSDC nucleotide sequence databases was also updated.
