Biotin ligase mechanism
WebMar 9, 2024 · A conserved regulatory mechanism in bifunctional biotin protein ligases BirA has been demonstrated for three bacterial strains. BirA signals to the global regulator Fur, which in turn activates LEE (locus of enterocyte effacement) genes to promote EHEC adherence in the low-biotin large intestine. WebAug 9, 2011 · Background: Biotin-dependent carboxylases are a diverse family of carboxylating enzymes widespread in the three domains of life, and thus thought to be very ancient. This family includes enzymes that carboxylate acetyl-CoA, propionyl-CoA, methylcrotonyl-CoA, geranyl-CoA, acyl-CoA, pyruvate and urea. They share a common …
