Abstract:
:The 16S ribosomal RNA mutation database (16SMDB) provides a list of mutated positions in 16S ribosomal RNA from Escherichia coli and the identity of each alteration. Information provided for each mutation includes: (i) a brief description of the phenotype(s) associated with each mutation; (ii) whether a mutant phenotype has been detected by in vivo or in vitro methods; (iii) relevant literature citations. The database is available via ftp and on the World Wide Web.
