Metabolite Identification
Common Namecarboxyspermidine
DescriptionCarboxyspermidine is a polyamine metabolite involved in the biosynthesis of spermidine, classified within the chemical class of polyamines. Its chemical structure features a carbon chain with multiple amine groups, which are crucial for its biological functions. Carboxyspermidine plays a significant role in alternative polyamine biosynthetic pathways, particularly in certain bacteria, where it is produced from putrescine through the action of carboxyspermidine dehydrogenase (CASDH) and carboxyspermidine decarboxylase (CASDC). These enzymes facilitate the conversion of putrescine into spermidine, with CASDH being primarily responsible for the production of spermidine from carboxyspermidine (PMID:40074085 ). In various human gut microbes, including Helicobacter pylori and Campylobacter jejuni, this alternative pathway is utilized instead of the classical route commonly found in eukaryotes (PMID:36283333 ). The metabolic pathway involving carboxyspermidine also includes the sequential conversion from arginine to agmatine, then to putrescine, and finally to carboxyspermidine (PMID:37314369 ). Overall, carboxyspermidine is a critical intermediate in polyamine metabolism, influencing cellular functions and growth in various microbial species.
