Autophagy regulates cellular processes in the setting of acute lung injury, sepsis, and oxidative stress by modulating the immune response and facilitating turnover of damaged cellular components.
Instead, we believe that the presence of the disordered region in AscG enhances the speed of interaction [30], [32] between AscG and AscF, which may facilitate turnover and allow for the rapid assembly of the needle complex subunit of the T3SS.
The matrix metalloproteinases (MMPs) are a family of 23 enzymes in man that facilitate turnover and breakdown of the ECM in both physiology and pathology.
The human MMPs are a family of 23 enzymes that facilitate turnover and breakdown of the ECM in both physiology and pathology.
A nearby arginine, R160, has previously been shown as playing a critical role in EAL catalysis.[ 15] Again, the formal (positive) charge of R160 is significant, with R160K retaining activity with a modest drop in kcat/ Km (∼180-fold) and R160A resulting in the accumulation of cob II)alamin but not facilitating turnover.
The UPS facilitates the turnover of proteins in several settings.
These results are consistent with a recent study showing that promoting lysosomal biogenesis facilitates Aβ turnover [ 51].
Both XAV939 and IWR are inhibitors of the poly-ADP-ribosylating enzyme tankryase, which facilitates Axin turnover by PARsylation-mediated ubiquitination and proteosomal degradation [ 156].
Vice versa, FAK facilitates p53 turnover via enhanced MDM2-dependent p53 ubiquitination, and subsequent proteosomal degradation leading to inactivation of p53 (Lim et al, 2008).
The protein protein interaction between the HRPKS and the releasing enzyme, which facilitates product turnover and chain length control, is therefore an intricate part of the overall programming rule of these enzymes.
