I need to classify some sequence entries from databases into
Gram-positive (single-membraned, such as B.subtilis) and Gram-negative
(double-membraned, such as E.coli) bacteria. SWISSPROT, however, does
not use those terms in the classification, instead it divides
PROKARYOTA into FIRMICUTES, GRACILICUTES (including ANOXYPHOTOBACTERIA,
OXYPHOTOBACTERIA, and SCOTOBACTERIA), MENDOSICUTES (= ARCHAEBACTERIA),
and TENERICUTES (= MYCOPLASMA). Do these groups relate to the Gram +/-
concept, and if so, how?
Would it e.g. be safe to say that FIRMICUTES = Gram+ and GRACILICUTES
(or maybe SCOTOBACTERIA) = Gram- ???
Answers will be greatly appreciated.
