Protein

2-hydroxy-3-keto-5-methylthiopentenyl-1-phosphate phosphatase

Gene

mtnX

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Dephosphorylates 2-hydroxy-3-keto-5-methylthiopentenyl-1-phosphate (HK-MTPenyl-1-P) yielding 1,2-dihydroxy-3-keto-5-methylthiopentene (DHK-MTPene).1 Publication

Catalytic activityi

2-hydroxy-5-(methylthio)-3-oxopent-1-enyl phosphate + H2O = 1,2-dihydroxy-5-(methylthio)pent-1-en-3-one + phosphate.

Pathwayi: L-methionine biosynthesis via salvage pathway

This protein is involved in step 4 of the subpathway that synthesizes L-methionine from S-methyl-5-thio-alpha-D-ribose 1-phosphate.
Proteins known to be involved in the 6 steps of the subpathway in this organism are:
  1. Methylthioribose-1-phosphate isomerase (mtnA)
  2. Methylthioribulose-1-phosphate dehydratase (mtnB)
  3. 2,3-diketo-5-methylthiopentyl-1-phosphate enolase (mtnW)
  4. 2-hydroxy-3-keto-5-methylthiopentenyl-1-phosphate phosphatase (mtnX)
  5. Acireductone dioxygenase (mtnD)
  6. Transaminase MtnE (mtnE)
This subpathway is part of the pathway L-methionine biosynthesis via salvage pathway, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-methionine from S-methyl-5-thio-alpha-D-ribose 1-phosphate, the pathway L-methionine biosynthesis via salvage pathway and in Amino-acid biosynthesis.
