Figure 2

Sequence alignment of Enterococus faecalis PTCase, Escherichia coli OTCase, Xanthomonas campestris AOTCase, Bacteroides fragilis SOTCase, E. coli ATCase and E. coli YTCase. Sequence encoding secondary structure elements (based on the E. faecalis PTCase structure) are indicated by boxes in yellow-green (β-strand) and red (α-helix). The conserved motifs, SxRT, HPxQ and HxLP across transcarbamylase members are indicated in blue. Nonconserved residues, which might be involved in binding substrates, are indicated in red. The 80’s, 120’s, proline-rich, 240’s and extra loops are boxed.
