WebDec 12, 2024 · As part of the Pr55Gag polyprotein, p6 fulfills an essential role in the late steps of the replication cycle. However, almost nothing is known about the functions of the mature HIV-1 p6 protein. Recently, we showed that p6 is a bona fide substrate of the insulin-degrading enzyme (IDE), a ubiquitously expressed zinc metalloprotease.

WebThis buffer works well because concentrations of the buffer components HCO. 3-and CO. 2 (formed from H. 2. CO. 3) are much greater than concentration of H + ions. This means that changes in the concentration of H + ions have little effect on the pH of blood. Other body organs play important roles in this buffer system. The lungs get rid of most ... WebBuffers resist changes in the pH of a solution when hydrogen ions or hydroxide are added (or removed). Buffers dissociate in solution and neutralize extra hydrogen ions or hydroxide ions by participating in reactions with them. Normal blood pH is 7.4, and arterial pH may only vary between 7.35 and 7.45 without being pathological.
