3.5.99.7 1-aminocyclopropane-1-carboxylate + H2O - 3.5.99.7 1-aminocyclopropane-1-carboxylate + H2O enzyme enhances nodulation of Pisum sativum, likely by modulating ethylene levels in the plant roots during the early stages of nodule development 3.5.99.7 1-aminocyclopropane-1-carboxylate + H2O the enzyme is thought to be intimately involved in the mechanism that the bacterium uses to promote root elongation in developing Canola seedlings. The enzyme is inducible by 1-aminocyclopropane-1-carboxylate and contains a basal level of constitutively expressed enzyme activity 3.5.99.7 1-aminocyclopropane-1-carboxylate + H2O effective induction by 1-aminocyclopropane-1-carboxylate and 2-aminobutanoate 3.5.99.7 1-aminocyclopropane-1-carboxylate + H2O the enzyme catalyzes the hydrolytic cleavage of 1-aminocyclopropane-1-carboxylate, the immediate precursor of ethylene, and is therefore an inhibitor of ethylene biosynthesis 3.5.99.7 1-aminocyclopropane-1-carboxylate + H2O the plant growth-promoting rhizobacteria stimulate plant growth through the activity of 1-aminocyclopropane-1-carboxylate deaminase 3.5.99.7 1-aminocyclopropane-1-carboxylate + H2O a precursor for ethylene production in plants 3.5.99.7 1-aminocyclopropane-1-carboxylate + H2O ACC deaminase activity is an important trait of plant growth-promoting rhizobacteria, PGPR, that stimulates root growth in infected plants, e.g. in soil-grown tomato Lycopersicon esculentum cv. Ailsa Craig. All the Pseudomonas brassicacearum strains studied cause pith necrosis when stems or fruits are inoculated with a bacterial suspension, as does the causal organism of this disease Pseudomonas corrugata strain 176, but the non-pathogenic strain Pseudomonas sp. Dp2 does not 3.5.99.7 1-aminocyclopropane-1-carboxylate + H2O deamination of the ethylene precursor in plants, regulation of enzyme activity involving the lrp-like leucine-responsive regulatory gene, called acdR, overview 3.5.99.7 1-aminocyclopropane-1-carboxylate + H2O the enzyme converts the precursor of ethylene production to 2-oxobutanoate and abolishes the response to ethylene in etiolated pea seedlings, which occurs after application of 1-aminocyclopropane-1-carboxylate in absence of the ACC deaminase, overview
