Abstract
Membrane dynamics are essential for the numerous cellular processes in eukaryotic and prokaryotic cells. Membrane fusion and fission are often catalysed by large GTPases of the dynamin protein families in eukaryotic cells, however the mechanisms responsible in prokaryotes are yet to be investigated in depth. With new results of the structural and biochemical data of prokaryotic dynamin-like proteins(DLPs) becoming available, this review summarizes current knowledge regarding prokaryotic dynamins, and discusses their structural and functional properties. The mechanisms how DLPs are involved in lipid droplets(LDs) formation and fission are investigated, and highlighted as a potential research area of LD dynamics. Based on these understandings, a hypothetical model is then described and further research analysis proposed.
