General Background

Polyamines are found in bacteria, archaea and eukaryotes and are necessary for normal cellular physiology. They include the diamine putrescine, the triamines spermidine, norspermidine (sym-norspermidine) and sym-homospermidine (homospermidine) and the tetraamine spermine (in [Shaw10] and in [Lee09c]). Links to their biosynthetic pathways can be found by clicking on these compounds links. See also superpathway of polyamine biosynthesis I, superpathway of polyamine biosynthesis II and superpathway of polyamine biosynthesis III. In members of the genus Vibrio, norspermidine is a major polyamine (in [Lee09c].

About This Pathway

In this pathway L-aspartate-semialdehyde donates a carboxyaminopropyl group to propane-1,3-diamine to form carboxynorspermidine in a reaction catalyzed by carboxynorspermidine/carboxyspermidine dehydrogenase (CANSDH). Decarboxylation of carboxynorspermidine catalyzed by carboxynorspermidine/carboxyspermidine decarboxylase (CANSDC) produces norspermidine. L-aspartate-semialdehyde is also a precursor for propane-1,3-diamine biosynthesis from L-2,4-diaminobutanoate which is catalyzed by a bifunctional fusion protein L-2,4-diaminobutyrate aminotransferase/decarboxylase (DABA AT/DC) ([Yamamoto86, Lee09c] and in [Shaw10]).

This L-aspartate-semialdehyde based pathway has been experimentally demonstrated in vivo in Vibrio cholerae including a branch of this pathway that leads to the biosynthesis of spermidine as shown in the pathway link. Both pathways are shown together in superpathway of polyamine biosynthesis III.

Heterologous expression in Escherichia coli of the genes encoding the enzymes in this pathway resulted in accumulation of propane-1,3-diamine and norspermidine (which are inactive polyamines in Escherichia coli). Deletion of the gene encoding CANSDC in Vibrio cholerae resulted in accumulation of carboxynorspermidine. Deletion of the genes encoding either CANSDC or CANSDH led to loss of norspermidine and spermidine, thus identifying the gene encoding CANSDH. Interestingly, deletion of the Vibrio cholerae genes encoding either CANSDH or CANSDC reduced the growth rate of planktonic cells by approximately 50% and severely reduced biofilm formation. Biofilm formation could be rescued by adding exogenous norspermidine, but not spermidine . The pathway did not appear to be related to the infectivity of Vibrio cholerae, using a mouse model [Lee09c]. Earlier work also suggested a role for norspermidine in biofilm formation in Vibrio cholerae [Karatan05].

Bioinformatic analysis suggested that DABA AT/DC fusion proteins and their clustering with CANSDH and CANSDC were found only in the family Vibrionaceae, giving support to their role in both spermidine and norspermidine biosynthesis in these organisms. However, a clustered pair of CANSDH and CANSDC genes was widespread in the α-, β-, γ-, δ- and ε-proteobacteria, firmicutes and a candidate division TG-1, suggesting that the pathway for spermidine biosynthesis may be more widely used. However, this conclusion could not be extended to norspermidine biosynthesis without experimental support due to the use of L-2,4-diaminobutanoate in other pathways (see ectoine biosynthesis, pyoverdine I biosynthesis and rhizobactin 1021 biosynthesis) [Lee09c].
