Catalysis of the reaction: 7,8-dihydromonapterin <=> glycolaldehyde + 2-amino-6-(hydroxymethyl)-7,8-dihydropteridin-4-ol.

The chemical reactions and pathways resulting in the formation of a C-terminal peptidyl-alanine ethanolamide-linked glycosylphosphatidylinositol (GPI) anchor following hydrolysis of an alanyl-peptide bond in the carboxy-terminal region of a membrane-associated protein.

Catalysis of the reaction: 4'-demethylrebeccamycin + S-adenosyl-L-methionine <=> H+ + rebeccamycin + S-adenosyl-L-homocysteine.

Catalysis of the reaction: (S)-scoulerine + O2 = dehydroscoulerine + hydrogen peroxide + H+.

Catalysis of the reaction: benzoate + L-glutamate + ATP <=> H+ + N-benzoyl-L-glutamate + AMP + diphosphoric acid.

Catalysis of the reaction: vanillate + L-glutamate(1-) + ATP <=> H+ + N-vanillate-L-glutamate + AMP + diphosphoric acid.

A ubiquitin ligase complex, located in the nucleus, in which a cullin from the Cul1 subfamily and a RING domain protein form the catalytic core; substrate specificity is conferred by a Skp1 adaptor and an F-box protein. SCF complexes are involved in targeting proteins for degradation by the proteasome. The best characterized complexes are those from yeast and mammals (with core subunits named Cdc53/Cul1, Rbx1/Hrt1/Roc1).

Binding to a protein from the structural maintenance of chromosomes (SMC) family, a group of chromosomal ATPases with a role in mitotic chromosome organization.

Regions within compact myelin in which the cytoplasmic faces of the enveloping myelin sheath are not tightly juxtaposed, and include cytoplasm from the cell responsible for making the myelin. Schmidt-Lanterman incisures occur in the compact myelin internode, while lateral loops are analogous structures found in the paranodal region adjacent to the nodes of Ranvier.

Catalysis of the endonucleolytic cleavage to give 5'-phosphooligonucleotide end-products, with a preference for cleavage within the sequence CC.

Catalysis of the exonucleolytic cleavage that removes extra residues from the 3'-terminus of tRNA to produce 5'-mononucleotides.

Catalysis of the endonucleolytic cleavage of poly(A) to fragments terminated by 3'-hydroxy and 5'-phosphate groups.

Non-compact myelin located adjacent to the nodes of Ranvier in a myelin segment. These non-compact regions include cytoplasm from the cell responsible for synthesizing the myelin. Lateral loops are found in the paranodal region adjacent to the nodes of Ranvier, while Schmidt-Lantermann clefts are analogous structures found within the compact myelin internode.

Catalysis of the endonucleolytic cleavage of poly(U) to fragments terminated by 3'-hydroxy and 5'-phosphate groups.

The portion of the myelin sheath in which layers of cell membrane are tightly juxtaposed, completely excluding cytoplasm. The juxtaposed cytoplasmic surfaces form the major dense line, while the juxtaposed extracellular surfaces form the interperiod line visible in electron micrographs.

Catalysis of the endonucleolytic cleavage of RNA, removing 3'-extranucleotides from tRNA precursor.

Catalysis of the two-stage endonucleolytic cleavage to nucleoside 3'-phosphates and 3'-phosphooligonucleotides with 2',3'-cyclic phosphate intermediates.
