RT nov., novel members of Usitatibacteraceae fam. nov. within the order
RT Nitrosomonadales isolated from soil.";
RL Submitted (APR-2020) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Translation factor necessary for the incorporation of
CC selenocysteine into proteins. It probably replaces EF-Tu for the
CC insertion of selenocysteine directed by the UGA codon. SelB binds GTP
CC and GDP. {ECO:0000256|ARBA:ARBA00025526}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496}.
