Polymyxins Revisited [PDF]

open access: yesClinical Microbiology Reviews, 2008
SUMMARY The global emergence of multidrug-resistant gram-negative bacilli has spurred a renewed interest in polymyxins. Once discarded due to concerns regarding nephrotoxicity and neurotoxicity, polymyxins now hold an important role in the antibiotic armamentarium.

Structures of Polymyxin B2 and Polymyxin E1 [PDF]

open access: yesNature, 1964
IN a previous communication1, from the analysis of a partial acid hydrolysate, the structure of polymyxin E1 was shown to be limited to two alternatives, the so-called 7 α and 8γ formulae. By applying the enzyme method of hydrolysis as devised by Suzuki et al. in their determinations of the structures of polymyxin B1 (ref. 2) and colistin A (ref.

SpxA1 and SpxA2 act coordinately to fine-tune stress responses and virulence in Streptococcus pyogenes [PDF]

open access: yes, 2017
SpxA is a unique transcriptional regulator highly conserved among members of the phylum Firmicutes that binds RNA polymerase and can act as an antiactivator. Why some Firmicutes members have two highly similar SpxA paralogs is not understood.
