Description: seryl-tRNA synthase
EC number: 6.1.1.11
Annotation score: 3 out of 5
Miscellaneous [CC]:
Protein existence: Inferred from homology
Catalytic activity: CATALYTIC ACTIVITY: ATP + L-serine + tRNA(Sec) = AMP + diphosphate + L-seryl-tRNA(Sec). {ECO:0000256|HAMAP-Rule:MF_00176}.; CATALYTIC ACTIVITY: ATP + L-serine + tRNA(Ser) = AMP + diphosphate + L-seryl-tRNA(Ser). {ECO:0000256|HAMAP-Rule:MF_00176}.
Cofactor:
Enzyme regulation:
Function [CC]: FUNCTION: Catalyzes the attachment of serine to tRNA(Ser). Is also able to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L-seryl-tRNA(Sec), which will be further converted into selenocysteinyl-tRNA(Sec). {ECO:0000256|HAMAP-Rule:MF_00176}.
Pathway: PATHWAY: Aminoacyl-tRNA biosynthesis; selenocysteinyl-tRNA(Sec) biosynthesis; L-seryl-tRNA(Sec) from L-serine and tRNA(Sec): step 1/1. {ECO:0000256|HAMAP-Rule:MF_00176}.
