Display the word mapDisplay the reaction diagram Show all sequences 2.1.1.173evolution the enzyme is a member of the COG1092 family, evolutionary implications of the apparent emergence of Escherichia coli YcbY from the fusion of Streptococcus mutans Smu472 and Smu776 orthologues are considered 720601
Display the word mapDisplay the reaction diagram Show all sequences 2.1.1.173malfunction deletion of rlmL/ycbY results in a slight growth reduction phenotype 720598
Display the word mapDisplay the reaction diagram Show all sequences 2.1.1.173malfunction insertions in both uup and ycbY confer a Uup- phenotype. It is concluded that ycbY and uup constitute a single operon and that the failure of the ycbY insertion to complement mutations in uup is because of a polarity effect associated with the former 704261

Growth competition with the parental wild-type strain leads to a gradual decrease in the knock-out strain cells proportion in the media 675411

Display the word mapDisplay the reaction diagram Show all sequences 2.1.1.173physiological function cooperative methylation of helix 74 by RlmKL plays a key role in the efficient assembly of the 50S subunit, RlmKL enzyme is an example of a methyltransferase catalyzing two mechanistically different types of RNA modification. RlmKL has an unwinding activity of Helix 74, facilitating cooperative methylations of m7G2069 and m2G2445 during biogenesis of 50S subunit. Methyltransferase RlmL, encoded by rlmL/ycbY, catalyzes S-adenosyl-L-methionine-dependent m2G2445 formation 720598
Display the word mapDisplay the reaction diagram Show all sequences 2.1.1.173physiological function it is likely that the G2445 modification is necessary for prevention of nonfunctional secondary or tertiary structure formation at the peptidyl transferase center 675411
Display the word mapDisplay the reaction diagram Show all sequences 2.1.1.173physiological function the N-terminal region of YcbY adds the m2G2445 modification, while the C-terminal region of YcbY is responsible for the m7G2069 methylation on the opposite side of the same helix, H74. YcbY enzyme is an example of a methyltransferase catalyzing two mechanistically different types of RNA modification 720601
