Organism
Vibrio alginolyticus (strain ATCC 17749 / DSM 2171 / NBRC 15630 / NCIMB 1903 / XII-53)
Function
Involved in norspermidine biosynthesis. Catalyzes the synthesis of carboxynorspermidine from L-aspartate 4-semialdehyde and 1,3-diaminopropane. Is also slightly active with putrescine as a substrate.
Similarity
Belongs to the saccharopine dehydrogenase family. carboxynorspermidine synthase subfamily.
