Fig. 3: Cryo-EM structure of the homodimeric globular domain of EXTL3.

EXTL3∆N was purified and subjected to cryo-EM single particle analysis, achieving a resolution of 2.4 Å. a Cryo-EM density map. Domains are coloured-coded as in Fig. 1a (GT47: dark grey; inter-domain linker: yellow; GT64 blue). b Fitted model, coloured-coded as in panel a. The N- and C-termini are labelled for each chain.
