| case <OC:Vertebrata> | |
| FUNCTION | Aminocarboxypropyltransferase that catalyzes the aminocarboxypropyl transfer on pseudouridine at position 1248 (Psi1248) in 18S rRNA. It constitutes the last step in biosynthesis of the hypermodified N1-methyl-N3-(3-amino-3-carboxypropyl) pseudouridine (m1acp3-Psi) conserved in eukaryotic 18S rRNA. |
| CATALYTIC ACTIVITY | Reaction=N(1)-methylpseudouridine(1248) in human 18S rRNA + S-adenosyl- L-methionine = H(+) + N(1)-methyl-N(3)-[(3S)-3-amino-3- carboxypropyl]pseudouridine(1248) in human 18S rRNA + S-methyl-5'- thioadenosine; Xref=Rhea:RHEA:63292, Rhea:RHEA-COMP:11639, Rhea:RHEA- COMP:16308, ChEBI:CHEBI:15378, ChEBI:CHEBI:17509, ChEBI:CHEBI:59789, ChEBI:CHEBI:74890, ChEBI:CHEBI:146234; PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:63293; |

It constitutes the last step in biosynthesis of the hypermodified N1-methyl-N3-(3-amino-3-carboxypropyl) pseudouridine (m1acp3-Psi) conserved in eukaryotic 18S rRNA. |
| CATALYTIC ACTIVITY | Reaction=N(1)-methylpseudouridine(1191) in yeast 18S rRNA + S-adenosyl- L-methionine = H(+) + N(1)-methyl-N(3)-[(3S)-3-amino-3- carboxypropyl]pseudouridine(1191) in yeast 18S rRNA + S-methyl-5'- thioadenosine; Xref=Rhea:RHEA:63300, Rhea:RHEA-COMP:13852, Rhea:RHEA- COMP:16309, ChEBI:CHEBI:15378, ChEBI:CHEBI:17509, ChEBI:CHEBI:59789, ChEBI:CHEBI:74890, ChEBI:CHEBI:146234; PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:63301; |
