FAMILY

branched-chain polyamine synthase family

DESCRIPTION

Also known as BPSA_THEKO, bpsA. Involved in the biosynthesis of branched-chain polyamines, which support the growth of thermophiles under high-temperature conditions. Catalyzes the sequential condensation of spermidine with the aminopropyl groups of decarboxylated S-adenosylmethionines to produce N(4)-bis(aminopropyl)spermidine via N(4)-aminopropylspermidine. Can also use spermine to produce N(4)-aminopropylspermine.
