A potential weakness of this study is the use of a constitutive active mutant of ER[alpha] to facilitate crystallography, which Arao suggests might alter the chemical-receptor interactions.
Zhang's team unexpectedly discovered an active mutant form of human Chk1, which is also a non-natural form of this gene.
Remarkably, the research team discovered that when expressed in cancer cells, this active mutant form of Chk1 permanently stopped cancer cell proliferation and caused cell death in petri dishes even without the addition of any chemotherapeutic drugs.
2000) also adapted the enzymatic diffusion zone method to select the active mutant for glucose oxidase activity.

To address this, transgenic mice were generated which over-express the [alpha]lA-AR with enhanced green fluorescent protein (EGFP) or constitutively active mutant (CAM) [alpha]lA-AR.
To further optimize TNXI's potential industrial utility random mutagenesis using the TNXI V185T-encoding gene as the template was performed and two highly active mutants 3A2 (V185T/L282P) and 1F1 (V185T/L282P/F186S) were obtained.
