There is little information on how TBCA might interact with beta-tubulin en route to microtubule biogenesis. To address this, the protozoan Leishmania major was targeted as a model system. The crystal structure of TBCA and comparisons with three orthologous proteins are presented. The presence of conserved features infers that electrostatic interactions that are likely to involve the C-terminal tail of beta-tubulin are key to association. This study provides a reagent and template to support further work in this area. The structure of tubulin-binding cofactor A from Leishmania major infers a mode of association during the early stages of microtubule assembly.,Barrack KL, Fyfe PK, Hunter WN Acta Crystallogr F Struct Biol Commun. 2015 May;71(Pt 5):539-46. doi:, 10.1107/S2053230X15000990.
