Welcome to the Mycoplasma genitalium database!

M. genitalium is a gram-positive bacterium and human pathogen. Among all freely-culturable organism, M. genitalium has the smallest genome, containing slightly more than 580 kb. Primarily due to its reduced genome size, M. genitalium has been the subject of intense research over the past thirty years. M. genitalium was the second organism to be completely sequenced, and the first organism to have its genome completely synthesized de novo and to be comprehensively modeled. M. genitalium's close relatives have also been the first to have their genome be transplated into a recipient cell. This PGDB provides a comprehensive description of M. genitalium molecular biology.

About WholeCellKB

WholeCellKB is a collection of free, open-source model organism databases designed specifically to enable comprehensive, dynamic simulations of entire cells and organisms. WholeCellKB provides comprehensive, quantitative descriptions of individual species including:

  • Cellular chemical composition,
  • Growth medium composition,
  • Gene locations, lengths, and directions,
  • Transcription unit organization and transcriptional regulation,
  • Macromolecule composition,
  • Reaction stoichiometry, kinetics, and catalysis, and
  • Extensive links and cross-links to all references used to construct each database.

WholeCellKB currently contains a single database of Mycoplasma genitalium, an extremely small gram-positive bacterium and common human pathogen. This database is the most comprehensive description of any single organism to date, and was used to develop the first whole-cell computational model. The M. genitalium database was curated from over 900 primary research articles, reviews, books, and databases over four years by a team of three researchers at Stanford University.
