|
|
|
|
|
|
||
| UniProt code: Q58933. |
|
||
| Organism: | |
Methanocaldococcus jannaschii (strain ATCC 43067 / DSM 2661 / JAL-1 / JCM 10045 / NBRC 100440) (Methanococcus jannaschii). |
| Taxonomy: | |
Archaea; Euryarchaeota; Methanomada group; Methanococci; Methanococcales; Methanocaldococcaceae; Methanocaldococcus. |
|
||
|
||
| Function: | |
Specifically phosphorylates seryl-tRNA(Sec) to O- phosphoseryl-tRNA(Sec), an activated intermediate for selenocysteine biosynthesis. {ECO:0000269|PubMed:16201757}. |
|
||
| Catalytic activity: | |
Reaction=ATP + L-seryl-tRNA(Sec) = ADP + O-phospho-L-seryl-tRNA(Sec); Xref=Rhea:RHEA:25037, Rhea:RHEA-COMP:9742, Rhea:RHEA-COMP:9947, ChEBI:CHEBI:30616, ChEBI:CHEBI:78533, ChEBI:CHEBI:78551, ChEBI:CHEBI:456216; EC=2.7.1.164; |
| Pathway: | |
Aminoacyl-tRNA biosynthesis; selenocysteinyl-tRNA(Sec) biosynthesis; selenocysteinyl-tRNA(Sec) from L-seryl-tRNA(Sec) (archaeal/eukaryal route): step 1/2. |
| Similarity: | |
Belongs to the L-seryl-tRNA(Sec) kinase family. {ECO:0000305}. |
| Sequence caution: | |
Sequence=AAB99557.1; Type=Erroneous initiation; Evidence={ECO:0000305}; |
