Enzyme Commission Number
EC 6.1.1.27
Product Overview
High-quality enzyme products.
Well-established quality management system.
Reaction
ATP + O-phospho-L-serine + tRNACys = AMP + diphosphate + O-phospho-L-seryl-tRNACys
Systematic Name
O-phospho-L-serine:tRNACys ligase (AMP-forming)
Function
In organisms like Archaeoglobus fulgidus lacking EC 6.1.1.16 (cysteine—tRNA ligase) for the direct Cys-tRNACys formation, Cys-tRNACys is produced by an indirect pathway, in which EC 6.1.1.27 (O-phosphoseryl-tRNA ligase) ligates O-phosphoserine to tRNACys, and EC 2.5.1.73 (O-phospho-L-seryl-tRNA: Cys-tRNA synthase) converts the produced O-phospho-L-seryl-tRNACys to Cys-tRNACys. The SepRS/SepCysS pathway is the sole route for cysteine biosynthesis in the organism. Methanosarcina mazei can use both pathways, the direct route using EC 6.1.1.16 (cysteine—tRNA ligase) and the indirect pathway with EC 6.1.1.27 and EC 2.5.1.73 (O-phospho-L-seryl-tRNA: Cys-tRNA synthase).
