Transglutaminases (Tgases) are a widely distributed group of enzymes that catalyse the
post-translational modification of proteins by the formation of isopeptide bonds. This occurs …

A review is presented of the recent developments in the metabolism andfunction of
polyamines in plants. Polyamines appear to be involved in a widerange of plant processes …

Copper (Cu) is a heavy metal which in recent studies has been attributed an increasing role
in metabolic processes of plant cells. It is an indispensable component of oxidative enzymes …

This chapter will focus on polyamine biosynthesis, oxidation, conjugation processes, mainly
to hydroxycinnamic acids, and compartmentation of enzymes, substrates and products …

The Chlamydomonas reinhardtii transcriptome was characterized from nutrient-replete and
sulfur-depleted wild-type and snrk2. 1 mutant cells. This mutant is null for the regulatory Ser …

In this review we will focus on two areas in which the accumulated evidence for a critical
physiological role of polyamines is becoming compelling, ie reproductive activity and …

The biocatalytic activity of transglutaminases (TGs) leads to the synthesis of new covalent
isopeptide bonds (crosslinks) between peptide-bound glutamine and lysine residues, but …

In contrast to animals, where polyamine (PA) catabolism efficiently converts spermine (Spm)
to putrescine (Put), plants have been considered to possess a PA catabolic pathway …

Data obtained in bacteria and mammals have revealed the existence of transcriptional,
translational and/or post‐translational mechanisms controlling polyamine metabolism. In …

An apple spermidine synthase (SPDS) gene (MdSPDS1) was verified to encode a functional
protein by the complementation of the spe3 yeast mutant, which lacks the SPDS gene. To …
