BtubA-BtubB heterodimer is an essential intermediate in protofilament assembly.

PloS one - 29 Sept 2009

Sontag Christopher A, Sage Harvey, Erickson Harold P

Abstract excerpt

BACKGROUND: BtubA and BtubB are two tubulin-like genes found in the bacterium Prosthecobacter. Our work and a previous crystal structure suggest that BtubB corresponds to alpha-tubulin and BtubA to beta-tubulin. A 1:1 mixture of the two proteins assembles into tubulin-like protofilaments, which f...
