The chemical reactions involving dermatan sulfate, any of a group of glycosaminoglycans with repeats consisting of beta-(1,4)-linked L-iduronyl-beta-(1,3)-N-acetyl-D-galactosamine 4-sulfate units. They are important components of ground substance or intercellular cement of skin and some connective tissues.

The formation from simpler components of chondroitin sulfate, any member of a group of 10-60 kDa glycosaminoglycans, widely distributed in cartilage and other mammalian connective tissues, the repeat units of which consist of beta-(1,4)-linked D-glucuronyl beta-(1,3)-N-acetyl-D-galactosamine sulfate.

The formation from simpler components of dermatan sulfate, any glycosaminoglycan with repeats consisting of beta-(1,4)-linked L-iduronyl-beta-(1,3)-N-acetyl-D-galactosamine 4-sulfate units.

Cleavage of the 5'-cap of an mRNA triggered by shortening of the poly(A) tail to below a minimum functional length.

Degradation of the mRNA transcript body that occurs when the ends are not protected by the 5'-cap or the 3'-poly(A) tail.

Catalysis of the reaction: 2 Fe2+ + NAD+ = 2 Fe3+ + NADH + H+.

mRNA catabolism, endonucleolytic cleavage-dependent decay

mRNA degradation, endonucleolytic cleavage-dependent decay

A minor mRNA degradation pathway that begins with an endonucleolytic cleavage to generate unprotected ends.

Transports adenine nucleotides (AMP, ADP, and ATP) across membranes.

Enables the directed movement of spermine into, out of, within or between cells. Spermine is a polybasic amine found in human sperm, in ribosomes and in some viruses, which is involved in nucleic acid packaging. Synthesis is regulated by ornithine decarboxylase which plays a key role in control of DNA replication.

Catalysis of the reaction: polyphosphate + n H2O = (n+1) oligophosphate. The product contains 4 or 5 phosphate residues.

integral to membrane of membrane fraction

Integral to that fraction of cells, prepared by disruptive biochemical methods, that includes the plasma and other membranes; require detergents, such as Triton X-100, to be released from membranes.
