  A Group of Aminotransferase Domain-Containing Proteins in Trichoderma harzianum Resembles Enzymes Catalyzing Acc Synthesis
  Author(s): Luis David Maldonado Bonilla*
  
  Production of phytohormones by plant-interacting Trichoderma species modifies the plant physiology to allow its colonization, and to promote plant growth and defense. Ethylene-dependent responses are triggered in plants inoculated with Trichoderma spp., but it is unclear whether such response is triggered by ethylene produced by Trichoderma itself. The rate-limiting step in ethylene biosynthesis is catalyzed by the enzyme 1-Aminocyclopropane- 1-Carboxylic Acid (ACC) Synthase (ACS). To gain insight into ethylene production in Trichoderma spp., the polypeptide sequences of six ACS-like proteins were identified in the endophytic T. harzianum. The identified ACS- like proteins have features of PLP-dependent enzymes and five of them conserve most of residues necessary to catalyze the biosynthesis of ACC. The predicted structure of ThACS-like1 illustrates.. View More»
