CC   -!- FUNCTION: Promotes the exchange of GDP for GTP in EF-1-alpha/GDP, thus
CC       allowing the regeneration of EF-1-alpha/GTP that could then be used to
CC       form the ternary complex EF-1-alpha/GTP/AAtRNA. {ECO:0000255|HAMAP-
CC       Rule:MF_00043}.
CC   -!- SIMILARITY: Belongs to the EF-1-beta/EF-1-delta family.
CC       {ECO:0000255|HAMAP-Rule:MF_00043}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAV45318.1; Type=Erroneous initiation; Evidence={ECO:0000305};
