Structure
Gastric lipase is a polypeptide of 371 residues in length. The structure of gastric lipase was determined using X-ray diffraction with a resolution of 3.00 Å, and is composed of 41% helices and 14% beta sheets. Gastric lipase belongs to the α/β-hydrolase-fold family. It possesses a classical catalytic triad (Ser-153, His-353, Asp-324) and an oxyanion hole (backbone NH groups of Gln-154 and Leu-67) analogous to serine proteases.

Famous quotes containing the word structure:
“Women over fifty already form one of the largest groups in the population structure of the western world. As long as they like themselves, they will not be an oppressed minority. In order to like themselves they must reject trivialization by others of who and what they are. A grown woman should not have to masquerade as a girl in order to remain in the land of the living.”
—Germaine Greer (b. 1939)
“Communism is a proposition to structure the world more reasonably, a proposition for changing the world. As such, we have to analyze it and, if we deem it reasonable, act upon it.”
—Friedrich Dürrenmatt (1921–1990)
“Vashtar: So it’s finished. A structure to house one man and the greatest treasure of all time.
Senta: And a structure that will last for all time.
Vashtar: Only history will tell that.
Senta: Sire, will he not be remembered?
Vashtar: Yes, he’ll be remembered. The pyramid’ll keep his memory alive. In that he built better than he knew.”
—William Faulkner (1897–1962)
