In the STEM images containing a single FMO, there is an apparent place for a second FMO, suggesting that some FMO is lost during preparation or the possibility of two distinct populations of the FMO/RCC complex.
As seen in Figure 4, zeaxanthin epoxidases are FAD-dependent mono-oxygenases (FMO) containing a putative lipocalin fold.
Eight IAA biosynthesis transcripts, encoding tryptophan biosynthesis 1 (TRP1), anthranilate synthase (ASB1), tryptophan synthase β-subunit 2 (TSB2), nitrilase 4 (NIT4), chorismatemutase (CM1), CYP79C1, YUC and FMO, showed a complex expression pattern throughout the cotton SE process.
The first group includes 24 proteins which sense stress signals and modulate redox state: many class III peroxidases, malate dehydrogenase, putative receptor-like proteins (RLPs), thiol redox-associated proteins (FMO and PDI), a chitinase and a pathogenesis-related protein (PR-1a).
Currently, we do not know whether this activity is a unique feature of the PNO of Grammia, or whether this conversion is an inherent activity of lepidopteran FMOs, suggesting a similar physiological role for lepidopteran FMOs as described for yeast and postulated for the FMOs of mammals and of Trypanosoma cruzi [69], [70].
The mass around 600 kDa can be explained by a complex with a 2 FMO 3(PscB)2(PscC 2PscD)2(Pscompositiontion with 48 molecules of BChl a in FMO, 16 molecules of BChl a, and 4 molecules of Chl a in RCC.
In vertebrates, FMOs form a gene family of five similar genes.
In plants, FMOs form a large gene family (29 genes in the model plant Arabidopsis thaliana), but information about their physiological role is sparse.
Graphical representation of the calculated FMOs of compounds 5 a– c and 6 a– c are shown in Figure 5.
The FMO method has an advantage of describing the charge-transfer between a receptor and a ligand in comparison to a conventional force field method using fixed atomic charges.
