Annual Review of Plant Biology, 2005
Recent research reveals that starch degradation in Arabidopsis leaves at night is significantly different from the “textbook” version of this process. Although parts of the pathway are now understood, other parts remain to be discovered. Glucans derived from starch granules are hydrolyzed via β-amylase to maltose, which is exported from the ...

To Degrade or Not to Degrade DNMT3A
Cancer Discovery, 2022Abstract Summary: Aberrant DNA cytosine methylation is a critical contributor to compromised tissue regeneration and malignant transformation, particularly during aging. In this issue of Cancer Discovery, Huang and colleagues define a new class of disease-associated DNA (cytosine-5-)-methyltransferase

Annual Review of Plant Physiology and Plant Molecular Biology, 1999
▪ Abstract Although the loss of green color in senescent leaves and ripening fruits is a spectacular natural phenomenon, research on chlorophyll breakdown has been largely neglected until recently. This review summarizes knowledge about the fate of chlorophyll in degreening tissues that has been gained during the past few years. Structures of end- and

Antioxidants & Redox Signaling, 2017
Glutathione degradation has for long been thought to occur only on noncytosolic pools. This is because there has been only one enzyme known to degrade glutathione (γ-glutamyl transpeptidase) and this localizes to either the plasma membrane (mammals, bacteria) or the vacuolar membrane (yeast, plants) and acts on extracellular or vacuolar pools. The last

Acta Oto-Laryngologica, 1983
During certain stages of mammalian inner ear development, small crystallized bodies which resemble otoconia may be found in the endolymphatic sac. In order to examine whether the endolymphatic sac plays any part in the process of degradation and dissolution of otoconia, we made an electron-microscopic examination on the endolymphatic sac of fetuses and

This chapter describes the degradative plasmids. Microorganisms play a major role in the degradation of the products and by-products of the activities of animals and plants and other microorganisms. The failure of microorganisms to rapidly recycle any of these compounds results in their accumulation in the environment and can lead to the phenomenon of ...

Hemoglobin degradation by Plasmodium is a massive catabolic process within the parasite food vacuole that is important for the organism's survival in its host erythrocyte. A proteolytic pathway is responsible for generating amino acids from hemoglobin.

Degradation Products in Degradable Polymers
Journal of Macromolecular Science, Part A, 1995Abstract Diffusion and migration of small molecules in polymers affect the long-term properties of the materials and also the surrounding environments. The interaction of such small molecules (i.e., low molecular weight compounds) with the environment are one of the main factors governing in-vitro and in-vivo behavior of degradable polymers.

Chloroplast degradation: one organelle, multiple degradation pathways
Trends in Plant Science, 2015Degradation of chloroplasts is a hallmark of both natural and stress-induced plant senescence. Autophagy and senescence-associated vacuoles are two established cellular pathways for chloroplast degradation. Recently, a third independent pathway for chloroplast degradation was reported.

The acidic aqueous degradation of the 7alpha-aminophenylglycinamido-containing cephalosporin cephalexin (1a) has been examined. Two major degradation products have been isolated and characterized: 3-formyl-3,6-dihydro-6-phenyl-2.5(1H,4H)-pyrazinedione (5) and 3-hydroxy-4-methyl-2(5H)-thiophenone (6).
