Other claims from this paper (7)
- Observation MAP2 bound taxol-stabilized maize microtubules, saturating at one MAP2 per five to six tubulin dimers.
- Observation Maize microtubules had a high-affinity MAP2 site 12 dimers apart.
- Observation Maize microtubules had an additional low-affinity site 12 dimers apart.
- Intervention effect MAP2 corrected in vitro folding errors in taxol-stabilized maize microtubules.
- Observation MAP2 dissociated more readily from maize than mammalian microtubules.
- Intervention effect MAP2 induced stable aberrant helical ribbon polymers of maize tubulin.
- Mechanism The authors infer partially specific, low-fidelity MAP2 binding to maize tubulin.
