CC   -!- FUNCTION: Catalyzes the biosynthesis of guanidinoacetate, the immediate
CC       precursor of creatine. Creatine plays a vital role in energy metabolism
CC       in muscle tissues. May play a role in embryonic and central nervous
CC       system development (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=glycine + L-arginine = guanidinoacetate + L-ornithine;
CC         Xref=Rhea:RHEA:13201, ChEBI:CHEBI:32682, ChEBI:CHEBI:46911,
CC         ChEBI:CHEBI:57305, ChEBI:CHEBI:57742; EC=2.1.4.1;
CC         Evidence={ECO:0000250|UniProtKB:P50440};
CC   -!- PATHWAY: Amine and polyamine biosynthesis; creatine biosynthesis;
CC       creatine from L-arginine and glycine: step 1/2.
CC       {ECO:0000250|UniProtKB:P50440}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P50440}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC       {ECO:0000250|UniProtKB:P50440}.
CC   -!- TISSUE SPECIFICITY: Ubiquitously expressed in adult tissues, with
CC       highest levels in muscle and intermediate levels in eye, heart, liver,
CC       stomach and testis. In stage 28 embryos, expression is higher in the
CC       dorsal and ventral parts of the trunk than in the head. In middle
CC       gastrulae, expression is highest around the yolk plug, while in stage
CC       15 and tailbud stage embryos, expression is largely restricted to the
CC       region around the presumptive notochord and gut.
CC       {ECO:0000269|PubMed:11466533}.
CC   -!- DEVELOPMENTAL STAGE: Expressed during embryonic development from the
CC       mid-gastrula stage onwards. {ECO:0000269|PubMed:11466533}.
CC   -!- SIMILARITY: Belongs to the amidinotransferase family. {ECO:0000255}.
