Candida rugosa lipase (triacylglycerol hydrolase) has been observed in two conformations, with the "lid" (residues 66-92[1]) closed (1trh) or open (1lpm)[1].
- Closed LID ().
- LID with inhibitor (1R)-menthyl hexyl phosphonate (C O P).
A morph[2] shows the lid opening and closing.
- (LID).
- (LID, catalytic triad: Ser209, Glu341, and His449[1]).
When the lid is closed, the enzyme surface is largely Polar. When the lid opens, a Hydrophobic pocket is exposed with the catalytic triad in the bottom.
- (Polar, Hydrophobic, catalytic triad: Ser209, Glu341, and His449[1]).
An alternate morph[3] shows a different path between the . The position of the inhibitor in the 1lpm structure is shown throughout; it would clash with the conformation of the lid in the 1trh structures, showing that closed lid and inhibitor binding are mutually exclusive.
