Spatial micro-compartmentation of Mo-cofactor biosynthesis complex is observed.
BiFC is used for interaction studies in the natural environment of cells.
Non-invasive labelling of cytoskeleton was performed via specific binding proteins.
Molybdenum insertase Cnx1 interacts with actin filaments but not with microtubules.
Cnx1 acts as bridge protein anchoring the biosynthesis complex on actin filaments.
