S-adenosyl-L-homocysteine hydrolase (AdoHcyase) is an enzyme of the activated methyl cycle, responsible for the reversible hydration of S-adenosyl-L-homocysteine into adenosine and homocysteine.
S-Adenosylmethionine synthetase, also known as methionine adenosyltransferase (MAT), is an enzyme that creates S-adenosylmethionine by reacting methionine and ATP.
S-methyl-5'-thioinosine phosphorylase is an enzyme with systematic name S-methyl-5'-thioinosine:phosphate S-methyl-5-thio-alpha-D-ribosyl-transferase. This enzyme catalyses the following chemical reaction
Thermospermine synthase (EC 2.5.1.79, TSPMS, ACL5 (ACAULIS5), SAC51) is an enzyme with systematic name S-adenosylmethioninamine:spermidine 3-aminopropyltransferase (thermospermine synthesizing). This enzyme catalyses the following chemical reaction
8-oxoguanine deaminase (EC 3.5.4.32, 8-OGD) is an enzyme with systematic name 8-oxoguanine aminohydrolase. This enzyme catalyses the following chemical reaction
Chlorophyllide a and Chlorophyllide b are the biosynthetic precursors of chlorophyll a and chlorophyll b respectively. Their propionic acid groups are converted to phytyl esters by the enzyme chlorophyll synthase in the final step of the pathway. Thus the main interest in these chemical compounds has been in the study of chlorophyll biosynthesis in plants, algae and cyanobacteria. Chlorophyllide a is also an intermediate in the biosynthesis of bacteriochlorophylls.
5'-deoxyadenosine deaminase is an enzyme that catalyzes the conversion of 5′-deoxyadenosine to 5′-deoxyinosine. To a lesser extent, the enzyme also catalyzes the deamination of 5′-methylthioadenosine, S-adenosylhomocysteine, and adenosine. The molecular mass of the DadD enzyme is approximately 230 kDa. DadD maintains 90% of its enzymatic activity after being heated at 60 degrees Celsius for ten minutes. The preferred pH for 5'deoxyadenosine deaminase is 9.0, with the enzyme denaturing at a pH of 11. The DadD enzyme has a preferred substrate of 5'deoxyadenosine, though it will also react with 5′-methylthioadenosine, S-adenosylhomocysteine, and adenosine at lower efficiencies.
