Dapi polyphosphate
WebApr 21, 2024 · Inorganic polyphosphate (polyP) is a significant regulatory and metabolic compound in yeast cells. We compared polyP content and localization, polyphosphatase activities, and transcriptional profile of polyP-related genes in industrially important methylotrophic yeasts, Hansenula polymorpha and Pichia pastoris. The increased need … WebWhen overstained with DAPI (long exposure or high concentration), polyphosphate granules were visible as yel- low fluorescence (Fig. 1E), while nuclear staining faded.

WebNov 13, 2007 · Polyphosphate (polyP) consists of tens to hundreds of phosphates, linked by ATP-like high-energy bonds. Although polyP is present in mammalian mitochondria, its physiological roles there are obscure. Here, we examine the involvement of polyP in mitochondrial energy metabolism and ion transport. WebPolyphosphates (polyP) are polymers of inorganic phosphates joined by high-energy bonds to form long chains. These chains are present in all forms of life but were once disregarded as ‘molecular...
