Comments [?]

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 RHEA:63292: 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
PhysiologicalDirection=left-to-right (RHEA:63293)
else case <OC:Fungi>
Function Aminocarboxypropyltransferase that catalyzes the aminocarboxypropyl transfer on pseudouridine at position 1191 (Psi1191) 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 RHEA:63300: 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
