Definition of metX

Curated proteins or TIGRFams with EC 2.3.1.31
Comment: MetX is often encoded next to a methyltransferase-like protein MetW. Because MetW is not consistently required for MetX's activity, it is not included in GapMind. MetW can bind MetX and increase its activity (PMID:33604638), and in some bacteria, there is tight cofitness between MetX and MetW, which suggests that MetW is required for MetX's activity (i.e., Paraburkholderia bryophila, many Pseudomonas, Caulobacter crescentus, or Sphingomonas koreensis). But in other diverse bacteria, metW mutants can still grow in minimal media (i.e., Herbaspirillum seropedicae or Cupriavidus necator), or have milder phenotypes than metX mutants (i.e., Burkholderia phytofirmans, Acidovorax 3H11, Dechlorosoma suillum PS, Marinobacter adhaerens).
