Many sporulation genes have close homologs in non-sporulating bacteria, including cyanobacteria, proteobacteria and spirochaetes, indicating that their products play a wider biological role. Most of them have been characterized as regulatory proteins or enzymes of peptidoglycan turnover; functions of others remain unknown but they are likely to have a general role in cell division and\/or development. We have compiled a list of such widely conserved sporulation and germination proteins with poorly characterized functions, ranked them by the width of their phylogenetic distribution, and performed detailed sequence analysis and, where possible, structural modeling aimed at estimating their potential functions. Here we report the results of sequence analysis of Bacillus subtilis spore germination protein GerM, suggesting that it is a widespread cell development protein, whose function might involve binding to peptidoglycan. GerM consists of two tandem copies of a new domain (designated the GERMN domain) that forms phylum-specific fusions with two other newly described domains, GERMN-associated domains 1 and 2 (GMAD1 and GMAD2). Fold recognition reveals a \u03b2-propeller fold for GMAD1, while ab initio modeling suggests that GMAD2 adopts a fibronectin type III fold. SpoVS is predicted to adopt the AlbA archaeal chromatin protein fold, which suggests that it is a DNA-binding protein, most likely a novel transcriptional regulator.<\/jats:p>\n               <jats:p>Contact: \u00a0drigden@liverpool.ac.uk<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary data are available at ftp:\/\/ftp.ncbi.nih.gov\/pub\/galperin\/Sporulation.html<\/jats:p>","DOI":"10.1093\/bioinformatics\/btn314","type":"journal-article","created":{"date-parts":[[2008,6,18]],"date-time":"2008-06-18T00:24:54Z","timestamp":1213748694000},"page":"1793-1797","source":"Crossref","is-referenced-by-count":33,"title":["Sequence analysis of GerM and SpoVS, uncharacterized bacterial \u2018sporulation\u2019 proteins with widespread phylogenetic distribution"],"prefix":"10.1093","volume":"24","author":[{"given":"Daniel J.","family":"Rigden","sequence":"first","affiliation":[{"name":"1 School of Biological Sciences, University of Liverpool, Crown St, Liverpool L69 7ZB, UK and 2NCBI, National Library of Medicine, National Institutes of Health, Bethesda, Maryland 20894, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael Y.","family":"Galperin","sequence":"additional","affiliation":[{"name":"1 School of Biological Sciences, University of Liverpool, Crown St, Liverpool L69 7ZB, UK and 2NCBI, National Library of Medicine, National Institutes of Health, Bethesda, Maryland 20894, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2008,6,17]]},"reference":[{"key":"2023020210501568700_B1","doi-asserted-by":"crossref","first-page":"7856","DOI":"10.1128\/JB.00837-07","article-title":"Predicted functions and linkage specificities of the products of the Streptococcus pneumoniae capsular biosynthetic loci","volume":"189","author":"Aanensen","year":"2007","journal-title":"J.
