Function

[PRMA_THET8] Methylates ribosomal protein L11; this reaction probably occurs before the protein is assembled into the ribosome. This function is dispensable for growth and thermostability. [RL11_THET8] One of the L7 dimers in conjuction with L11 and its bound segment of 23S rRNA forms what is known as the L7/L12 stalk, which extends beyond the surface of the 70S ribosome. The stalk is preferentially stabilized in 70S versus 50S crystals.[HAMAP-Rule:MF_00736_B] This protein binds directly to 23S ribosomal RNA.[HAMAP-Rule:MF_00736_B] In the 70S ribosome is in a position where it could interact transiently with the A site tRNA during translation.[HAMAP-Rule:MF_00736_B]

Publication Abstract from PubMed

Ribosomal protein L11 is a universally conserved component of the large subunit, and plays a significant role during initiation, elongation, and termination of protein synthesis. In Escherichia coli, the lysine methyltransferase PrmA trimethylates the N-terminal alpha-amino group and the epsilon-amino groups of Lys3 and Lys39. Here, we report four PrmA-L11 complex structures in different orientations with respect to the PrmA active site. Two structures capture the L11 N-terminal alpha-amino group in the active site in a trimethylated post-catalytic state and in a dimethylated state with bound S-adenosyl-L-homocysteine. Two other structures show L11 in a catalytic orientation to modify Lys39 and in a noncatalytic orientation. The comparison of complex structures in different orientations with a minimal substrate recognition complex shows that the binding mode remains conserved in all L11 orientations, and that substrate orientation is brought about by the unusual interdomain flexibility of PrmA.
