The protein

Catalyzed reaction/ biological activity

• YoaD is likely to convert 3-phosphoglycerate to serine for use in methionine biosynthesis (based on [protein|search|S-box] regulation)

Structure

• [PDB|1WWK] (phosphoglycerate dehydrogenase from Pyrococcus horikoshii, 35% identity)

Additional information

• The gene is annotated in KEGG as an ortholog of D-3-phosphoglycerate dehydrogenase EC 1.1.1.95. No EC annotation is available in Swiss-Prot. In MetaCyc the protein is marked as “similar to phosphorglycerate dehydrogenase”. No literature/experimental evidence supporting the annotation is available. [Pubmed|19935659]

  regulatory mechanism

  • [regulon|S-box|S-box]: termination, the [SW|S-box] [SW|riboswitch] binds S-adenosylmethionine resulting in termination [Pubmed|10094622], in [regulon|S-box|S-box]

  regulation

  • induced by methionine starvation ([SW|S-box]) [Pubmed|10094622]
  • the [SW|S-box] RNA is degraded by [protein|872CCB5A49C9000BD95E4B0472556D5F60F7D7A4|RNase Y] [pubmed|29794222]
