The guinea pig pancreatic lipase-related protein 2 (GPLRP2) differs from classical pancreatic lipases in that it displays both lipase and phospholipase A1 activities; classical pancreatic lipases have no phospholipase activity. The sequence of GPLRP2 is 63 % identical to that of human pancreatic lipase (HPL), but the so-called lid domain, is much reduced in GPLRP2. A phospholipase A1 from hornet venom (Dolml PLA1) is very similar to HPL and GPLRP2 but is devoid of lipase activity; Dolml PLA1 also contains a reduced lid domain and lacks a region termed the beta9 loop, which is located in the vicinity of the HPL and GPLRP2 active sites. The structure determination of a chimera of GPLRP2 and HPL and domain building of Dolml PLA1 were undertaken to gain a better understanding of the structural parameters responsible for the differences in lipase versus phospholipase activity among these structurally related enzymes.
