“…UW4 ACC deaminase presented a molecular weight of ~41 kDa and showed a K M = 3.4 ± 0.2 mM and k cat = 146 ± 5 min −1 at pH 8.0 and 22 • C. The strain UW4 enzyme was thermodynamically stable presenting a melting temperature of 58 ± 1 • C. The Pseudomonas sp. UW4 ACC deaminase K M and k cat values are comparable to those of other ACC deaminase-producing bacteria (Table 2), including Methylobacterium strains [71] and Amycolatopsis methanolica 239 [72]. However, the enzyme of Pseudomonas sp.…”

“…The inoculation of mini-carnation cut flowers with the ACC deaminase-producing endophytes, P. brassicacearum YsS6 and P. migulae 8R6, resulted in a delay in flower senescence of several days, and, consequently, an increased flower shelf-life [72]. These effects were not observed when the plants were inoculated with the respective Pseudomonas acdS − mutants of these strains [77].…”

The expression of the enzyme 1-aminocylopropane-1-carboxylate (ACC) deaminase, and the consequent modulation of plant ACC and ethylene concentrations, is one of the most important features of plant-associated bacteria. By decreasing plant ACC and ethylene concentrations, ACC deaminase-producing bacteria can overcome some of the deleterious effects of inhibitory levels of ACC and ethylene in various aspects of plant-microbe interactions, as well as plant growth and development (especially under stressful conditions). As a result, the acdS gene, encoding ACC deaminase, is often prevalent and positively selected in the microbiome of plants. Several members of the genus Pseudomonas are widely prevalent in the microbiome of plants worldwide. Due to its adaptation to a plant-associated lifestyle many Pseudomonas strains are of great interest for the development of novel sustainable agricultural and biotechnological solutions, especially those presenting ACC deaminase activity. This manuscript discusses several aspects of ACC deaminase and its role in the increased plant growth promotion, plant protection against abiotic and biotic stress and promotion of the rhizobial nodulation process by Pseudomonas. Knowledge regarding the properties and actions of ACC deaminase-producing Pseudomonas is key for a better understanding of plant-microbe interactions and the selection of highly effective strains for various applications in agriculture and biotechnology.
