Figure 5: Scheme for post-translational transit complex targeting to the thylakoid membrane.
From: Structural basis for cpSRP43 chromodomain selectivity and dynamics in Alb3 insertase interaction
(a) Schematic representation of cpSRP43 interactions with linear motifs in post-translational targeting. Flexibility in absence of the binding partners between ankyrin repeats and CD2, and between CD2 and CD3 is indicated with black arrows. (b) Scheme for transit complex interactions at the thylakoid membrane. CpSRP54 establishes the connection to the SRP receptor cpFtsY via targeting complex formation, whereas A3CT tethers the transit complex to the Alb3 insertase within the membrane.
