Purification (Commentary)

EC Number Purification (Comment) Organism
5.6.1.3 the purified protein co-sediments with microtubules, but the majority of the protein remains in the supernatant in the absence of microtubules, indicating that the motor domain of BC12 binds microtubules Oryza sativa Japonica Group

5.6.1.3 additional information
-
 the enzyme activity is proportional to the amount of microtubules. The motor domain with the stalk region shows higher enzyme activity than the motor domain alone in the presence of 0.04 mg of microtubules, suggesting that BC12 has microtubule-dependent ATPase activity and that the neck linker is critial for this activity Oryza sativa Japonica Group

General Information

EC Number General Information Comment Organism
5.6.1.3 physiological function BC12 functions as a dual-targeting kinesin protein and is implicated in cell-cycle progression, cellulose microfibril deposition and wall composition in the monocot plant rice. Perturbation of BC12 produces defects in cell number/plant height and mechanical properties. BC12 has a conserved ATPase-driven motor domain that is required for bindung to and moving along the microtubules Oryza sativa Japonica Group
