Arabidopsis auxin-resistance gene AXR1 encodes a protein related to ubiquitin-activating enzyme E1

Article Abstract:

Map-based isolation of the AXRI gene shows that the AXRI encodes a new protein with significant sequence, similar to the ubiquitin-activating enzyme, EI. The AXRI protein is different from the EI enzymes and does not have a cysteine residue that is imperative for EI activity. It is assumed that either the AXRI is a new class of enzyme in the ubiquitin pathway or it has a role in cellular regulation, unconnected to ubiquitin conjugation.

Sticking with auxin

Article Abstract:

The crystallographic studies about auxin, the main agent that regulate plant growth and development is conducted to provide more revelations about auxin perception and the auxin receptor. The findings reveal that auxin hormone acts as a molecular glue in mediating substrate-receptor interactions.
