Fig. 8From: Portability of the thiolation domain in recombinant pyoverdine non-ribosomal peptide synthetasesMass spectra obtained from the supernatant of each of the T1 domain substitution strains. Arrows indicate peaks at 991.5 or 1333.6Â m/z, corresponding to the masses of the previously detected truncated and wild-type pyoverdine species, respectivelyBack to article page
