Transglutaminases: Widespread Cross-linking Enzymes in Plants

Abstract

The widespread occurrence of transglutaminases activity in all organs and cell compartments studied suggests a relevance for their still incompletely defined physiological roles. At present, it is not possible to classify this enzyme family in plants owing to the scarcity of information on genes encoding them.

Polyamines: potent modulators of plant responses to stress

“…Therefore, PAs are likely to play a role in photosynthesis since they are capable of reversing stress-induced damages in photosynthetic apparatus (Sfakianaki et al 2006). Cross-linking of PAs mediated by transglutaminases might play a significant role in polyamine bioactivity for flower development and compatibility in reproduction (Serafini-Fracassini and Del Duca 2008). Thus, conjugates involved in defense mechanisms against abiotic and biotic and also mediate the regulation of certain growth and developmental events (Bagni & Tassoni 2001;Martin-Tanguy 2001).…”

Structural and Phylogenetic Analyses of the GP42 Transglutaminase from Phytophthora sojae Reveal an Evolutionary Relationship between Oomycetes and Marine Vibrio Bacteria

“…TGase activity has been implicated in a multitude of physiological activities in animals, plants, and bacteria (1)(2)(3). Human TGases such as the blood coagulation factor XIIIa or the tissue TGase 2 have been structurally characterized (4,5).…”

“…TGases are widespread in microorganisms, plants, vertebrate and invertebrate animals [Serafi ni-Fracassini & Del Duca, 2008]. TGase activity has been found in higher and lower plants [Del Duca & Serafi ni-Fracassini, 2005].…”
