Sequence alignment of Cypl-like proteins. hyor, M. hyorhinis; geni, M. genitalium; hyop, M. hyopneumoniae; pneu, M. pneumoniae; pene, Mycoplasma penetrans. Sequences are highlighted to indicate percentage identity and consensus. Symbols above columns denote residues involved in hydrogen bonding interactions: ○, TPP binding; *, Ca site A; and §, Ca site B. Dark, medium, and light grey indicate 100%, 80%, and 60% identity, respectively. The figure was generated using Jalview (6).
