CC -!- FUNCTION: Specifically methylates position 2 of adenine 2503 in CC 23S rRNA and position 2 of adenine 37 in tRNAs. CC {ECO:0000255|HAMAP-Rule:MF_01849}. CC -!- CATALYTIC ACTIVITY: 2 S-adenosyl-L-methionine + adenine(2503) in CC 23S rRNA + 2 reduced [2Fe-2S] ferredoxin = S-adenosyl-L- CC homocysteine + L-methionine + 5'-deoxyadenosine + 2- CC methyladenine(2503) in 23S rRNA + 2 oxidized [2Fe-2S] ferredoxin. CC {ECO:0000255|HAMAP-Rule:MF_01849}. CC -!- CATALYTIC ACTIVITY: 2 S-adenosyl-L-methionine + adenine(37) in CC tRNA + 2 reduced [2Fe-2S] ferredoxin = S-adenosyl-L-homocysteine + CC L-methionine + 5'-deoxyadenosine + 2-methyladenine(37) in tRNA + 2 CC oxidized [2Fe-2S] ferredoxin. {ECO:0000255|HAMAP-Rule:MF_01849}. CC -!- COFACTOR: CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; CC Evidence={ECO:0000255|HAMAP-Rule:MF_01849}; CC Note=Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 CC cysteines and an exchangeable S-adenosyl-L-methionine. CC {ECO:0000255|HAMAP-Rule:MF_01849}; CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01849}. CC -!- MISCELLANEOUS: Reaction proceeds by a ping-pong mechanism CC involving intermediate methylation of a conserved cysteine CC residue. {ECO:0000255|HAMAP-Rule:MF_01849}. CC -!- SIMILARITY: Belongs to the radical SAM superfamily. RlmN family. CC {ECO:0000255|HAMAP-Rule:MF_01849}.
