Abstract
Branched-chain polyamines (BCPAs) are unique polycations found in (hyper)thermophiles. Thermococcus kodakarensis grows optimally at 85 °C and produces the BCPA N4-bis(aminopropyl)spermidine by sequential addition of decarboxylated S-adenosylmethionine (dcSAM) aminopropyl groups to spermidine (SPD) by BCPA synthase A (BpsA). The T. kodakarensis bpsA deletion mutant (DBP1) did not grow at temperatures at or above 93 °C, and grew at 90 °C only...
