the long-chain polyamines stabilize double-stranded DNA at high temperatures |
2.5.1.127 | S-adenosyl 3-(methylthio)propylamine + norspermidine |
the long-chain polyamines stabilize double-stranded DNA at high temperatures |
2.5.1.127 | S-adenosyl 3-(methylthio)propylamine + norspermine |
the long-chain polyamines stabilize double-stranded DNA at high temperatures |
2.5.1.127 | S-adenosyl 3-(methylthio)propylamine + spermidine |
spermidine is not the most preferred substrate for any enzyme. Nevertheless, in vivo the enzyme can be responsible for the synthesis of thermospermine, if spermidine is present in a high concentration in competition to other accepted polyamines |
