A Novel Putrescine Utilization Pathway Involves γ-Glutamylated Intermediates of Escherichia coli K-12

Abstract: A novel bacterial putrescine utilization pathway was discovered. Seven genes, the functions of whose products were not known, are involved in this novel pathway. Five of them encode enzymes that catabolize putrescine; one encodes a putrescine importer, and the other encodes a transcriptional regulator. This novel pathway involves six sequential steps as follows: 1) import of putrescine; 2) ATP-dependent ␥-glutamylation of putrescine; 3) oxidization of ␥-glutamylputrescine; 4) dehydrogenation of ␥-glutamyl-␥-am… Show more

“…6, supplemental Table 8). Slr1022 shows strong similarity to the proteins (YgjG and SpuC) involved in degradation of putrescine into aminobutyrate in E. coli and Pseudomonas (55,56). Further evidence that succinate is produced from arginine came from the strong up-regulation of succinate dehydrogenase and malate dehydrogenase (Fig.…”

“…Putrescine is known to play a critical role in DNA, RNA, and protein synthesis, as well as in cell proliferation and differentiation. Furthermore, putrescine serves as a source for carbon and nitrogen in E. coli and Pseudomonas (55,56), where it is converted to succinate. Examination of proteins involved in putrescine degradation suggested that this pathway is also active in Synechocystis (Fig.…”

“…Also, the putrescine degrading Puu pathway, which is responsible for catabolizing extracellular putrescine (Kurihara et al, 2005) in wild-type E. coli, was deleted; the puuPA genes that encode the dorminant putrescine importer PuuP and glutamate-putrescine ligase (PuuA; the first enzyme of the Puu pathway). However, an alternative putrescine degradation pathway involving YgjG and YdcW was not deleted because its activity is negligible (Kurihara et al, 2008).…”

“…Putrescine can be degraded through the Puu pathway with g-glutamylation (Kurihara et al, 2005) and the YdcW-YgjG pathway without g-glutamylation (Samsonova et al, 2003(Samsonova et al, , 2005. Moreover, putrescine is utilized as a precursor for the biosynthesis of other polyamines such as spermidine (Fig.…”

“…PotE is responsible for both the excretion and uptake of putrescine (18). PuuP is the most recently discovered putrescine transporter and depends on proton motive force (19,20). In addition, two putative putrescine importers, YdcSTUV and YeeF, have been annotated by computer analysis.…”
