CC   -!- FUNCTION: eIF-2 functions in the early steps of protein synthesis by
CC       forming a ternary complex with GTP and initiator tRNA.
CC       {ECO:0000255|HAMAP-Rule:MF_00232}.
CC   -!- SUBUNIT: Heterotrimer composed of an alpha, a beta and a gamma chain.
CC       {ECO:0000255|HAMAP-Rule:MF_00232}.
CC   -!- SIMILARITY: Belongs to the eIF-2-beta/eIF-5 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00232}.
