CC -!- FUNCTION: Aminocarboxypropyltransferase that catalyzes the
CC aminocarboxypropyl transfer on pseudouridine corresponding to position
CC 914 in M.jannaschii 16S rRNA. It constitutes the last step in
CC biosynthesis of the hypermodified N1-methyl-N3-(3-amino-3-
CC carboxypropyl) pseudouridine (m1acp3-Psi). {ECO:0000255|HAMAP-
CC Rule:MF_01116}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=an N(1)-methylpseudouridine in 16S/18S rRNA + S-adenosyl-L-
CC methionine = H(+) + N(1)-methyl-N(3)[(3S)-3-amino-3-
CC carboxypropyl]pseudouridine in 16S/18S rRNA + S-methyl-5'-
CC thioadenosine; Xref=Rhea:RHEA:63296, Rhea:RHEA-COMP:11634, Rhea:RHEA-

CC ChEBI:CHEBI:74890, ChEBI:CHEBI:146234; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01116};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01116}.
CC -!- SIMILARITY: Belongs to the TDD superfamily. TSR3 family.
CC {ECO:0000255|HAMAP-Rule:MF_01116}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAC11172.1; Type=Erroneous initiation; Evidence={ECO:0000305};
