Prof Eric Gaucher of Georgia Tech, US, helped with the ancestral gene sequence reconstruction and commented: "A gene can become deactivated by as few as one or two mutations.
In contrast, cholecalciferol [now 1,24,25(OH)3D3] retains its capacity to bind to the VDR (8) and still requires an additional side-chain oxidation to become deactivated (25).
We have revised the text to: "The fact that this self-matching spacer is tolerated in this organism implies that either the proto-spacer associated motif (PAM) has been mutated in the chromosomal gene sequence rendering the gene immune [ 3] or that the chromosomal CRISPR/Cas system had become deactivated in this archaeon".
It closely resembles the "default system" that has been defined in human functional imaging studies as a system of areas that become deactivated from a resting "default" condition in most tasks that involve external attention to objects or events outside the individual (e.g., Gusnard et al. 2001; Fox et al. 2005).

(Uber says it already abides by this requirement in Maryland). Drivers would also be required to return their Uber and Lyft decals if their accounts became deactivated.
The results confirm that Ni/YSZ becomes deactivated at 76 h, but the catalysts with the Rh promoter have much higher durability.
So, whereas the Cu/NaZSM-5 exhibits a high NO conversion at the reaction temperatures (573 and 873 K), the parent Cu/NaY zeolite becomes deactivated in the first stages of reaction.
