negative regulation of protein catabolism

Any process that stops, prevents or reduces the rate of the breakdown into simpler components of a protein by the destruction of the native, active configuration, with or without the hydrolysis of peptide bonds.

The action of a molecule that contributes to the structural integrity of bone.

The specification of male sex of an individual organism.

Structure or material found in the flagella of mammalian sperm that surrounds each of the nine microtubule doublets, giving a 9 + 9 + 2 arrangement rather than the 9 + 2 pattern usually seen. These dense fibers are stiff and noncontractile.

The intramolecular conversion of uridine to pseudouridine within an RNA molecule. This posttranscriptional base modification occurs in tRNA, rRNA, and snRNAs.

The chemical reactions involving retinoids, any member of a class of isoprenoids that contain or are derived from four prenyl groups linked head-to-tail. Retinoids include retinol and retinal and structurally similar natural derivatives or synthetic compounds, but need not have vitamin A activity.

Blood vessel formation when new vessels emerge from the proliferation of pre-existing blood vessels.

Extracellular matrix components occurring independently or along with elastin. Thought to have force-bearing functions in tendon. In addition to fibrillins, microfibrils may contain other associated proteins.

Catalysis of the cleavage of interstitial collagens in the triple helical domain. Unlike EC:3.4.24.7, this enzyme cleaves type III collagen more slowly than type I.

The processes involved in removing superoxide radicals (O2-) from a cell or organism, e.g. by conversion to dioxygen (O2) and hydrogen peroxide (H2O2).

Catalysis of the reaction: R-CH2-NH2 + H2O + O2 = R-CHO + NH3 + H2O2.

Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
