CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=GTP + H2O = GDP + H(+) + phosphate; Xref=Rhea:RHEA:19669,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:37565,
CC         ChEBI:CHEBI:43474, ChEBI:CHEBI:58189; EC=3.6.5.2;
CC         Evidence={ECO:0000250|UniProtKB:P01112};
CC   -!- ACTIVITY REGULATION: Alternates between an inactive form bound to GDP
CC       and an active form bound to GTP. Activated by a guanine nucleotide-
CC       exchange factor (GEF) and inactivated by a GTPase-activating protein
CC       (GAP).
CC   -!- SUBCELLULAR LOCATION: Cell membrane; Lipid-anchor.
CC   -!- DEVELOPMENTAL STAGE: In sporulating mycelium and much less in germling
CC       and yeast.
CC   -!- SIMILARITY: Belongs to the small GTPase superfamily. Ras family.
CC       {ECO:0000305}.
