(CMA). A selective autophagy pathway in which proteins that contain a signal KFERQ-like sequence are targeted by HSAP8/HSC70 chaperones and translocated into lysosomes via LAMP2A. Transcription factor EB (TFEB). A protein that plays a pivotal role in the regulation of basic cellular processes,...
One such is the primary lysosome also called the true, pure, or original lysosome. The primary lysosomes, however derived, contain hydrolytic enzymes but no substrate to act upon. Structures in which the enzymes confront substrates and digestion ensues are the secondary lysosomes. There are two ...
The digestion of macromolecules is carried out through an intense concentration of enzymes. To be specific, lysosomes contain close to 50 different degrading enzymes that are capable of hydrolyzing proteins, DNA, RNA, polysaccharides, and lipids within the cell.1 All of lysosomal enzymes are acid ...
Lysosomes are an important component of the inner membrane system and participate in numerous cell biological processes, such as macromolecular degradation, antigen presentation, intracellular pathogen destruction, plasma membrane repair, exosome release
The lytic enzymes including ribonuclease, deoxyribonuclease, phosphatases, cathepsin, lysozyme, sulphatases, and glycosidases are stored in central vacuole of lysosome, which is surrounded by a dense granulated stroma. These enzymes are commonly called acid hydrolases because they activate at acidic pH,...
autophagy occurs when the cell consumes part of itself). The product of the endosome-autophagosome fusion is called an amphisome. The completed autophagosome or amphisome fuses with a lysosome, which supplies acid hydrolases. The enzymes in the resulting compartment, an autolysosome, break down the ...
Lysosomes contain over 60 hydrolytic enzymes including proteases, nucleases, lipases, glycosidases, phospholipases, and phosphatases. Collectively, these enzymes are called acid hydrolases, as they are active at lysosomal acidic environment (pH 4.8), but not at the neutral cytoplasmic pH (7.2) [10...
The membrane enclosing the plant cell vacuole is called the tonoplast. Like lysosomes, plant cell vacuoles contain hydrolytic enzymes. In addition, they usually contain sugars, salts, acids, and nitrogenous compounds such as alkaloids and anthrocyanin pigments. The pH of the pla...

Vesicles containing lysosomal enzymes bud off from the trans-Golgi network and fuse with endosomes (which contain material brought into the cell by endocytosis) to form mature lysosomes. 點擊卡片即可翻轉 👆 建立者 tpidell 3個月前建立 學生們也學習了 ...
