Phosphoribosylaminoimidazole carboxylase
Phosphoribosylaminoimidazole carboxylase (or AIR carboxylase) is an enzyme involved in nucleotide biosynthesis and in particular in purine biosynthesis. It catalyzes the conversion of 5′-phosphoribosyl-5-aminoimidazole (AIR) into 5′-phosphoribosyl-4-carboxy-5-aminoimidazole (CAIR) as described […]
Adenosylmethionine decarboxylase
Adenosylmethionine decarboxylase is an enzyme that catalyzes the conversion of S-adenosyl methionine to S-adenosylmethioninamine.Polyamines such as spermidine and spermine are essential for cellular growth under most conditions being implicated in […]
Cystathionine gamma-lyase
Cystathionine gamma-lyase (or cystathionase) is an enzyme which breaks down cystathionine into cysteine and α-ketobutyrate. Pyridoxal phosphate is a prosthetic group of this enzyme.
Adenosylhomocysteinase
Adenosylhomocysteinase (EC 3.3.1.1 S-adenosylhomocysteine synthase S-adenosylhomocysteine hydrolase adenosylhomocysteine hydrolase S-adenosylhomocysteinase SAHase AdoHcyase) is an enzyme that converts S-adenosylhomocysteine to homocysteine and adenosine. This enzyme catalyses the following chemical reaction S-adenosyl-L-homocysteine […]
Neuregulin 1
Neuregulin 1 or NRG1 is a protein that in humans is encoded by the NRG1 gene. NRG1 is one of four proteins in the neuregulin family that act on the […]
Sib RNA
Sib RNA refers to a group of related non-coding RNA. They were originally named QUAD RNA after they were discovered as four repeat elements in Escherichia coli intergenic regions. The […]
7SK RNA
In molecular biology 7SK is an abundant small nuclear RNA found in metazoans. It plays a role in regulating transcription by controlling the positive transcription elongation factor P-TEFb. 7SK is […]
Guanine deaminase
Guanine deaminase (EC 3.5.4.3 guanase guanine aminase GAH guanine aminohydrolase) is an enzyme which converts guanine to xanthine.
Uracil phosphoribosyltransferase
Uracil phosphoribosyltransferase is an enzyme which creates UMP from uracil and phosphoribosylpyrophosphate. This protein may use the morpheein model of allosteric regulation.
