The polyamines, found in virtually all living organisms, are a ubiquitous group of compounds that appear to play a vital role in many cellular processes involving nucleic acids including cell growth and differentiation. The polyamines, found in virtually all living organisms, are a ubiquitous group of compounds that appear to play a vital role in many cellular processes involving nucleic acids including cell growth and differentiation. Acetylation on the terminal nitrogen adjacent to the 4-carbon chain produces N8-acetylspermidine. This reaction is catalyzed by spermidine N8-acetyltransferase and does not result in the conversion of spermidine to putrescine but, instead, the product undergoes deacetylation.

This reaction is catalyzed by methionine adenosyltransferase. L methione is taken up from the environment through a complex reaction coupled transport and then proceeds too synthesize the s adenosylmethionine through a adenosylmethionine synthase. The S-adenosylmethionine then interacts with a hydrogen ion through a adenosylmethionine decarboxylase resulting in a carbon dioxide and a S-adenosyl 3-methioninamine.This compound interacts with a putrescine through a spermidine synthase resulting in a spermidine, a hydrogen ion and a S-methyl-5'-thioadenosine. The latter compound is degraded by interacting with a water molecule through a 5' methylthioadenosine nucleosidase resulting in a adenine and a S-methylthioribose which is then release into the environment PW000837 Metabolic Specdb::CMs 2800 Specdb::CMs 157667 Specdb::NmrOneD 328232 Specdb::NmrOneD 328233 Specdb::NmrOneD 328234 Specdb::NmrOneD 328235 Specdb::NmrOneD 328236 Specdb::NmrOneD 328237 Specdb::NmrOneD 328238 Specdb::NmrOneD 328239 Specdb::NmrOneD 328240 Specdb::NmrOneD 328241 Specdb::NmrOneD 328242 Specdb::NmrOneD 328243 Specdb::NmrOneD 328244 Specdb::NmrOneD 328245 Specdb::NmrOneD 328246 Specdb::NmrOneD 328247 Specdb::NmrOneD 328248 Specdb::NmrOneD 328249 Specdb::NmrOneD 328250 Specdb::NmrOneD 328251 Specdb::MsMs 25346 Specdb::MsMs 25347 Specdb::MsMs 25348 Specdb::MsMs 31904 Specdb::MsMs 31905 Specdb::MsMs 31906 Specdb::MsMs 445676 Specdb::MsMs 445677 Specdb::MsMs 445678 Specdb::MsMs 445679 Specdb::MsMs 445680 Specdb::MsMs 2236905 Specdb::MsMs 2364922 Specdb::MsMs 2364923 Specdb::MsMs 2364924 Specdb::MsMs 2597737 Specdb::MsMs 2597738 Specdb::MsMs 2597739 HMDB02189 123689 110264 C01029 27911 CPD-3462 Q9C Hrushesky WJ, Merdink J, Abdel-Monem MM: Circadian rhythmicity of polyamine urinary excretion.
