The latter must be activated by a cellular enzyme, and cells vary greatly in their ability to do so.

The only effect they seemed to have was to replace many of the cellular enzymes.

Aldehyde reductase is the cellular enzyme that protects the body from 3DG.

In addition, he noted, an important cellular enzyme, guanylyl cyclase, has heme at its center.

But the cellular enzymes that copy the DNA in the chromosomes have a problem with the chromosome ends, called telomeres, and cannot copy them completely.

But it is possible that its overexpression impairs the ability of the insulin receptor to activate cellular enzymes.

The RNA is located at a radius of 6 nm and is protected from the action of cellular enzymes by the coat protein.

The loss of cell structure brings about the release of cellular enzymes capable of initiating the breakdown of surrounding cells and tissues.

The researchers found that hydroxyurea inhibited the synthesis of deoxynucleotides, the building blocks of DNA, by blocking a cellular enzyme.

Disadvantages include more exposure to cellular defenses, leading to possible degradation of viral gene via cellular enzymes.
