Putrescine and spermidine transport in Leishmania

Molecular and Biochemical Parasitology, 2000
The transport of putrescine and spermidine into Leishmnania donovani promastigotes and Leishmania mexicana promastigotes and amastigotes has been characterised. Polyamine transport was shown to be saturable and temperature-sensitive for both developmental stages of Leishmania.

Enzymic assay for spermine and spermidine

Analytical Biochemistry, 1966
Abstract This paper describes a sensitive enzymic micromethod for the quantitative assay of spermine and spermidine. The method is based on the oxidation of the polyamines by serum amine oxidase. The aminoaldehydes produced during the oxidation are assayed by N -methyl-2-benzothiazolone hydrazone hydrochloride, at 660 mμ.

Spermidine: A constituent of the myelin sheath?

Neuroscience Letters, 1978
Abstract Spermidine, an aliphatic polyamine present in high concentrations in the white matter, could act as a bivalent ligand stabilizing myelin lamellae. To seek an answer to the title's question, polyamines were extracted from the subcellular fractions of rat brain after intracerebral injection of [14C]putrescine, a precursor of spermidine ...

Structure and Mechanism of Spermidine Synthases

Biochemistry, 2007
Aminopropyltransferases transfer aminopropyl groups from decarboxylated S-adenosylmethionine to amine acceptors, forming polyamines. Structural and biochemical studies have been carried out with the human spermidine synthase, which is highly specific for putrescine as the amine acceptor, and the Thermotoga maritima spermidine synthase, which prefers ...

A New Pathway for the Biosynthesis of Spermidine

Biochemical Society Transactions, 1976
The only pathway known for the biosynthesis of sperrnidine is from putrescine and S-adenosylmethionine. S-Adenosylmethionine is decarboxylated, and the aminopropyl group of the product is transferred to putrescine to form spermidine. The enzymes of this pathway, S-adenosylmethionine decarboxylase (EC 4.1.1 S O ) and aminopropyltransferase (EC 2.5.1.16),
