Table 2.

Alignment of several members of the GDSL lipase family

The three residues highlighted in bold type (‘S’ in Block I, ‘D’ in Block III and ‘H’ in Block V) represent the catalytic triad conserved in GDSL lipases.The additional spaces have been inserted to maintain the correct sequence alignment.
