CC -!- FUNCTION: A methylase, recognizes the double-stranded sequence 5'-
CC YTCGAR-3', methylates C-3 on both strands, and protects the DNA from
CC cleavage by the BsuMI endonuclease. {ECO:0000269|PubMed:11751814,
CC ECO:0000269|PubMed:3150363, ECO:0000269|PubMed:32324221}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 2'-deoxycytidine in DNA + S-adenosyl-L-methionine = a 5-
CC methyl-2'-deoxycytidine in DNA + H(+) + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:13681, Rhea:RHEA-COMP:11369, Rhea:RHEA-COMP:11370,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:85452, ChEBI:CHEBI:85454; EC=2.1.1.37;
CC -!- ACTIVITY REGULATION: Somewhat inhibited by MgCl(2) and spermidine,
CC strongly inhibited by MnCl(2). {ECO:0000269|PubMed:3150363}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=0.6 uM for S-adenosyl-L-methionine {ECO:0000269|PubMed:3150363};
CC KM=3 nM for DNA {ECO:0000269|PubMed:3150363};
CC pH dependence:
CC Optimum pH is 8.0. {ECO:0000269|PubMed:3150363};
CC Temperature dependence:
CC Rapidly loses activity at 37 degrees Celsius in the absence of DNA.
CC {ECO:0000269|PubMed:3150363};
CC -!- SUBUNIT: Monomer (PubMed:3150363). May form a complex with YdiP, also
CC seems to be active alone (Probable). {ECO:0000269|PubMed:3150363,
CC ECO:0000305|PubMed:11751814}.
CC -!- DEVELOPMENTAL STAGE: Not expressed during sporulation.
CC {ECO:0000269|PubMed:11751814}.
CC -!- INDUCTION: Constitutively expressed during exponential growth. Encoded
CC in an operon with ydiP and in a second with groES, groEL, ydiM and
CC ydiN. This second operon is heat-inducible.
CC {ECO:0000269|PubMed:11751814}.
CC -!- DISRUPTION PHENOTYPE: Essential for growth, it can be disrupted once
CC one of the components of the corresponding BsuMI restriction
CC endonuclease complex (AC O34303, O34885, O35025, YdjA, YdiS and YdiR
CC respectively) has been disrupted (PubMed:11751814). Triple deletions
CC ydiO-ydiP-ydiR, ydiO-ydiP-ydiS and ydiO-ydiP-ydjA lead to loss of
CC susceptibility to MspJI, which only digests C-methylated DNA
CC (PubMed:32324221). {ECO:0000269|PubMed:11751814,
CC ECO:0000269|PubMed:32324221}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. C5-methyltransferase family. {ECO:0000255|PROSITE-
CC ProRule:PRU01016}.
CC -!- CAUTION: The characterized enzyme was reported to be a monomer of
CC approximately 45 kDa; it is not clear whether this corresponds to YdiO,
CC YdiP or to another activity altogether. {ECO:0000305|PubMed:3150363}.
