Bacillaenum
Bacillaenum (Anglice: bacillaene) est antibioticum ex Bacillo subtili natum, primum anno 1995 agnitum.[1] Bacillaenum est molecula linearis cum duo nodis amidis: primus acidum α-hydroxy-carboxylicum et ω-acidum aminocarboxylicum religat, quod hexaenum coniugatum continet, et alter acidum carboxylicum religat quod hexaenum continet et acidum (ω-1)-carboxylicum, quod trienum coniugatum continet.[2] Bacillaenum contra latum bacteriorum spectrum in spectationibus diffusionis in catino agaroso agit. Investigationes in vitro indicant hoc antibioticum synthesin proteini prokaryotici, sed non synthesin proteini eukaryotici, inhibere.
Congeries genorum ≈80-kb pksX Bacillo subtili inusitatam synthasin peptidi? polyketidi/nonribosomalis? hybridam (hybrid polyketide/nonribosomal peptide synthase) insignit, quae ad productionem bacillaeni antibiotici et non circumscripti adligata est.
