However, other functions, such as the degradation of aromatic compounds [ 22], could not be excluded.
These genomic islands allow fast dissemination of genes involved in specific ecological functions, such as the degradation of recalcitrant organic molecules, or the resistance to different solvents or antibiotics (Toussaint et al. 2003).
The major function of protein ubiquitination is the signalling of protein degradation associated with cellular house-keeping functions such as the elimination of damaged proteins.
These proteins have a wide spectrum of functions, such as degradation of proteins in the retinal pigmented epithelium (RPE), ionic interchange, trafficking of molecules in the ribbon synapse of photoreceptors and many others.
Functional experiments showed that important community functions, such as cobalamin biosynthesis, the degradation of cellulose and the oxidation of As III) are redundant in the ecosystem thus increasing the functional robustness essential for any ecosystem.
Proteinase 3 has many functions, such as degradation of extracellular matrix proteins [ 11], platelet activation [ 12], induction of apoptosis [ 13], and increase of TNF- α and IL-1 β release [ 14].
In addition, carboxylesterases can serve as noncatalytic adhesive proteins involved in cell-to-cell interactions [ 5] and participate in other functions, such as pheromone degradation in moths [ 7] and hydrolysis of the neurotransmitter acetylcholine and juvenile hormone (JH) [ 8, 9].
Cellular functions such as RNA degradation and lipid metabolism were also affected during the study.
Serine proteases of the chymotrypsin family, for example, are involved in multiple physiological functions such as digestion, degradation, blood clotting, immunity, and development [ 34].
Although it is experimentally difficult to quantify the measure of stochasticity involved in different biological functions, it is a well-known fact that some functions, such as proteasome degradation, are least prone to stochasticity while functions, such as scaffolding complexes that integrate signals arising from different pathways, are likely to behave most stochastically.
P62 is a multifunctional protein involved in multiple cellular functions such as signal transduction and the degradation of both proteins and organelles.
