FunFam 207: 2,3-diketo-5-methylthio-1-phosphopentane phosphata...

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Acireductone synthase. [EC: 3.1.3.77]
5-(methylthio)-2,3-dioxopentyl phosphate + H(2)O = 1,2-dihydroxy-5- (methylthio)pent-1-en-3-one + phosphate.
  • This bifunctional enzyme first enolizes the substrate to form the intermediate 2-hydroxy-5-(methylsulfanyl)-3-oxopent-1-enyl phosphate, which is then dephosphorylated to form the acireductone 1,2- dihydroxy-5-(methylsulfanyl)pent-1-en-3-one.
  • The acireductone represents a branch point in the methione salvage pathway as it is used in the formation of formate, CO and 3-(methylsulfanyl)propanoate by EC 1.13.11.53 and of formate and 4-(methylsulfanyl)-2-oxobutanoate either by a spontaneous reaction under aerobic conditions or by EC 1.13.11.54.
