a, Phylogeny of LCIB. Numbers above branches are bootstrap support values (branches thickened when bootstrap >70). b, Hornwort LCIBs have conserved amino acid residues at the active site. Yellow and green arrowheads point to the zinc-binding and catalytic residues, respectively. K.n., K. nitens; C.r., C. reinhardtii; O.l., Ostreococcus lucimarinus.
