Bacteriorhodopsin ( br ) is the sole protein present in the purple membrane of halobacterium halobium . the biological function of the br is acted as a light - driven proton pump 細菌視紫紅質(zhì)( bacteriorhodopsin ,簡稱br )是嗜鹽菌細胞膜上的一種光敏蛋白質(zhì),具有光驅(qū)動質(zhì)子泵功能。
The applicability of endoscopic therapy in bleeding peptic ulcer is greatly enhanced with the discovery of helicobacter pylori and powerful ulcer healing drugs such as proton pump inhibitors 另一方面,隨著確立了幽門螺旋菌對胃病的影響及一些有效的治療胃潰瘍藥物的成功研制,內(nèi)鏡治療的用途更廣泛。
A proton pump is an integral membrane protein that is capable of moving protons across a cell membrane, mitochondrion, or other organelle. Mechanisms are based on conformational changes of the protein structure or on the Q cycle.
