abstract = {Gliding, a type of motility based on an actin-myosin motor,
is specific to apicomplexan parasites. Myosin A binds two
light chains which further interact with glideosome
associated proteins and assemble into the glideosome. The
role of individual glideosome proteins is unclear due to the
lack of structures of larger glideosome assemblies. Here, we
investigate the role of essential light chains (ELCs) in
Toxoplasma gondii and Plasmodium falciparum and present
their crystal structures as part of trimeric sub-complexes.
We show that although ELCs bind a conserved MyoA sequence,
P. falciparum ELC adopts a distinct structure in the free
and MyoA-bound state. We suggest that ELCs enhance MyoA
performance by inducing secondary structure in MyoA and thus
stiffen its lever arm. Structural and biophysical analysis
reveals that calcium binding has no influence on the
structure of ELCs. Our work represents a further step
towards understanding the mechanism of gliding in
Apicomplexa.},
