RL Submitted (JUN-2017) 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}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:OWZ83940.1}.
