CC       (bacterial route): step 1/1. {ECO:0000255|HAMAP-Rule:MF_00423}.
CC   -!- SUBUNIT: Homodecamer; pentamer of dimers. Binds only one seryl-
CC       tRNA(Sec) per dimer. {ECO:0000255|HAMAP-Rule:MF_00423}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00423}.
CC   -!- SIMILARITY: Belongs to the SelA family. {ECO:0000255|HAMAP-
