Fungal Phospholipase B-like; cPLA2 GrpIVA homologs; catalytic domain. Fungal phospholipase B are Group IV cPLA2 homologs. Aspergillus PLA2 is Ca-dependent, yet it does not contain a C2 domain. PLB deacylates both sn-1 and sn-2 chains of phospholipids and are abundantly expressed in fungi. It shows lysophospholipase (lysoPL) and transacylase activities. The active site residues from cPLA2 are also conserved in PLB. Like cPLA2, PLB also has a consensus sequence of Sm-X-Nu-Sm (Sm = small residue, X = any residue and Nu = nucleophile). It includes PLB1 from Schizosaccharomyces pombe, PLB2 from Candida glabrata, and PLB3 from Saccharomyces cerevisiae. PLB1, PLB2, and PLB3 show PLB and lysoPL activities; PLB3 is specific for phosphoinositides.
No pairwise interactions are available for this conserved domain.
Tips:  If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position. The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs. Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below. Range on the Protein: Protein ID Protein Position Domain Position:
