Mechanism of FabA. In this mechanism, H70 acts as a base to abstract the C2 proton whereas D84 protonates the leaving group in the first half of the reaction. Subsequently, D84 acts as a base to abstract a proton fromC4 leading to the formation of the 3-c s-enoyl-ACP product following reprotonation of C2 by H70. As proposed by Kimbereta ., the proximity of C4 to D84 is essential for the isomerization reaction and in FabZ C4 may not be close enough to the carboxylate of E63 for the latter to function as a base. Note that the elimination is syn and involves abstraction of the pro-2S proton from the substrate. Reproduced with permission from M. Leesong B. S. Flenderson J. R. Gillig J. M. Schwab J. L.

Mechanism of facilitated diffusion mediated by a glucose transporter. This is an example of uniport. The reversible interconversion between conformations of the transporter in which the glucosebinding site is alternately exposed to the exterior and interior of the cell is called a ping-pong mechanism.

Mechanism of fatty-acyl-CoA synthesis.

Mechanism of ferritin degradation and iron release. The degradation of ferritin nanocage probably occurs lysosomal and or proteasomal. Ferritin basal turnover, iron chelation and nutrition starvation stimulates ferritin degradation through the lysosomal pathways. While ferroportin overexpression, aging and oxidative stress causes ferritin degradation via proteasome-mediated pathways. Once iron is released from the ferritin nanocage, it will used for various metabolic processes.
