### FUNCTION One of the primary rRNA binding proteins, it binds directly to 16S rRNA central domain where it helps coordinate assembly of the platform of the 30S subunit ### SEQUENCE -M-M-Q-D-P-I-S-D-M-L-T-R-I-R-N-A-Q-A-V-R-K-K-E-V-V-M-P-R-S-K-L-K-M-S-I-A-N-V-L-K-E-E-G-Y-I-V-D-Y-R-E-E-G-D-L-T-K-A-Q-L-V-I-T-L-K-Y-H-E-G-E-S-V-I-S-E-I-R-R-V-S-S-P-A-L-Q-V-Y-K-S-K-D-E-L-P-K-V-K-N-G-L-G-I-A-I-I-S-T-S-K-G-V-M-S-D-R-Q-A-R-R-L-G-E-G-G-E-V-L-C-Y-V-S


### FUNCTION This is 1 of the proteins that binds and probably mediates the attachment of the 5S RNA into the large ribosomal subunit, where it forms part of the central protuberance In the 70S ribosome it contacts protein S13 of the 30S subunit , connecting the 2 subunits ### SEQUENCE -M-V-E-L-Q-E-L-Y-K-K-T-I-T-P-A-L-Q-K-E-F-G-F-K-S-V-M-A-V-P-R-L-E-K-I-T-L-N-M-G-L-G-E-A-V-A-D-K-K-V-I-E-R-A-M-D-D-M-I-K-I-S-G-Q-K-P-L-I-T-Y-A-R-K-S-E-A-G-F-K-I-R-A-G-W-P-I-G-C-K-V-T-L-R-R-D-R-M-Y-E-F-L-K-R-L-I-S-I-A-I-P-R-I-R-D-F-R-G-L-S-P-K-S-F-D-G-R-G-N-Y-S-L-G-I-R-E-Q-I-V-F-P-E-I-Q-Y-D-K-V-D-A-I-R-G-M-D-I-T-I-T-T-T-A-R-T-D-E-E-G-R-A-L-L-K-A-F-G-F-P-L-K-D-E-S-R


### FUNCTION One of two assembly initiator proteins, it binds directly to the 5'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit ### SEQUENCE -M-A-I-K-K-I-K-K-D-D-T-V-I-V-I-T-G-R-D-K-G-R-Q-G-K-V-L-K-V-L-P-N-S-R-L-L-V-E-G-I-N-L-V-K-K-H-V-K-P-N-P-N-K-N-E-Q-G-G-I-L-E-R-E-L-S-I-H-V-S-N-V-A-I-Y-N-P-A-A-K-K-A-D-R-V-G-I-K-T-L-E-D-G-S-K-V-R-I-F-K-S-N-G-E-V-I-D-V
