From a strictly metabolic standpoint, fermentations are microbially catalysed catabolic reactions in which a substrate is broken down in the absence of an external electron acceptor (such as oxygen, nitrate, or sulphate), generating energy by substrate-level phosphorylation (El-Mansi et al....
What is an example of substrate-level phosphorylation? Examples of substrate-level phosphorylation are theremoval of inorganic phosphates from 1,3-biphosphoglycerate or phosphoenolpyruvate to form 3-phosphoglycerate or pyruvate, respectively, as well as ATP. What occurs in the absence of oxygen? One o...
from Chapter 12 / Lesson 5 227K Learn to differentiate substrate-level phosphorylation vs. oxidative phosphorylation. Know the importance of substrate-level phosphorylation for cellular energy. Understand the importance of substrate-level phosphorylation for cellular energy. Related...

Endothelial cells (ECs) lining all blood vessels are subjected to large mechanical stresses that regulate their structure and function in health and disease. Here, we review EC responses to substrate-derived biophysical cues, namely topography, curvature
The cultured cells expressed ELK-1 and activated MEK for about 3 days and, thus, are likely to have achieved a steady state level of phosphorylation. Although the experimental conditions were quite different, the results were almost identical. All three ELK-1 substrates containing FQFP in the ...
N-terminal acetylation is one of the most common protein modifications in eukaryotes and is carried out by N-terminal acetyltransferases (NATs). It plays important roles in protein homeostasis, localization, and interactions and is linked to various huma
For example, Sindbis virus RNA polymerase is produced during viral infection through site-specific cleavage of the viral polyprotein precursor and carries an N-terminal Tyr that has been shown in rabbit reticulocyte lysates to target the protein for ubiquitylation via the N-end rule pathway (de...
