Phenotypes of a mutant

• no detectable phenotype [Pubmed|10869096]

The protein

Catalyzed reaction/ biological activity

• phosphatase involved in isopentenol (isoprenoid) biosynthesis

Protein family

• similar to 2,3-diphosphoglycerate-dependent phosphoglycerate mutases [Pubmed|10869096]

Structure

• [PDB|1H2F] (enzyme of ''B. stearothermophilus'') [Pubmed|11827481]

Additional information

• The gene is annotated in KEGG as an ortholog of phosphoglycerate mutase (PGM) EC 5.4.2.1. In MetaCyc the protein is marked as similar to phosphoglycerate mutase. No EC annotation is available in Swiss-Prot. Pearson et al. ([Pubmed|10869096]) demonstrated that yhfR is non-essential for growth, sporulation, and spore germination. They also purified the gene, expressed it in ''B. subtilis'' but were not able to detect PGM activity in ''B. subtilis''. [Pubmed|19935659]
