Investigation
of the KS1–ACP1–KS2 domain of LnmI
PKS module 3 at the LnmI NRPS–PKS interface for LNM biosynthesis
by site-directed mutagenesis in vivo. (A) HPLC analysis of LNM production
from KS1 or KS2 mutants as well as the complementation strains: I,
SB3036 (C2090A); II, SB3037 (H2959A); III, SB3038 (C2824A); IV, SB3045;
V, SB3046; VI, SB3047; VII, S. atroolivaceus S-140 wild-type; VIII, LNM standard (●). (B) HPLC analysis
of LNM production from the ACP1 mutants: I, SB3039; II, SB3040; III,
SB3041; IV, SB3042; V, SB3043; VI, SB3044; VII, S.
atroolivaceus S-140 wild-type; VIII, LNM standard
(●).
