Central common polyamine synthesis pathways in prokaryotes. ADC – arginine decarboxylase, ARG – arginase, ODC – ornithine decarboxylase, AGM – agmatinase, ADI – agmatine deiminase, NCPAH – N-carbamoylputrescine amidohydrolase, CASDH – carboxyspermidine dehydrogenase, CASDC – carboxyspermidine decarboxylase, PAPT – polyamine aminopropyltransferase, MAT – methionine adenosyltransferase, SAMDC – S-adenosylmethionine decarboxylase, LDC – lysine decarboxylase; AdoMet – S-adenosylmethionine, AdoMetDC – decarboxylated S-adenosylmethionine
