Normally, iron-containing enzymes have three amino acids iron iron in the active site avanafil 100mg . In this enzyme, however, one of the typical amino acid with a much shorter with a much shorter. That smaller spare more room in the active site can – enough space for the halide, in this case a chloride ion, to casually slip inside and bind to the iron, without the big theatrics chemists had expected. After the iron and chloride bind, the protein closes down around the active site, effectively the trigger of the gun. We were surprised Drennan said. To catalyze the change in the activity of an enzyme a halogenation is be require so radical that people thought it must be a very complicated difference in their structures. But it is just a small amino acid change in the active site. Things are usually not as easy, but it’s an elegant beauty in this simplicity, and it may be what gives other enzymes the prowess to manufacture other medicinally valuable halogenated substances required.
The recent crystallography MIT chemistry Associate Professor Catherine L. Drennan , the detective work, the mystery of the enzyme enviable abilities come to light, and it seems almost anti-climactic. It is simply a matter of size of one of its parts. – ‘If an enzyme is a gun that fires cause a reaction, then we have the mechanism chlorine. Pulls the trigger, ‘Drennan said. ‘In chemistry, we often see ‘molecules in, molecules. ‘With halogenated substances, but we could not figure out how it happened, because the chemicals are so reactive. Because we have the structure of the enzyme and found out how it works, it makes sense. But it is not what we predicted. ‘.
