Results of these studies have shown that this enzyme exists as a homodimer in solution.

"This enzyme existed in animal species from twenty-five million years back - right?"

However more recent data suggest that the enzyme may exist as a larger complex, possibly an octamer, comprising all three subunits.

Biochemists pooh-poohed the idea, arguing that if the enzymes existed they would already have found them.

Lysosomal disorders are triggered when a particular enzyme exists in too small an amount or is missing altogether.

The enzyme exists as a tetramer of identical subunits, each containing a possible type 2 copper-binding site.

The notion that an enzyme might exist in a number of forms decided purely on probability is anathema to many scientists.

The enzyme exists in a cytoplasmic form in a wide range of plants, animals, and fungi.

The enzyme exists as a homotetramer of ca.

In the corn seedling, the nitrate-reducing enzyme exists in small amounts.
