ORGANISM

COMMENTARY 
LITERATURE
IMAGE
2,4-pteridinediol
-
i.e. lumazine, competitively activates the enzyme with respect to ascorbate
alpha-aminoisobutryric acid
activates enzyme ACCO, prevents enzyme inactivation
bovine serum albumin
-
stimulates the recombinant enzyme by 41% at 0.1 mM
-
dihydrojasmonate
-
exogenously applied onto fruit skin, it induces the enzyme and the ethylene production in fruits at day 0 of ripening, in the climacteric stage at day 20 of ripening at 20°C the ethylene production increases without enzyme induction in trested and untreated fruits, overview
indole acetic acid
-
0.1 mM, increases level of ACO2 transcript in vivo, not ACO1
methyl jasmonate
0.02 mM methyl jasmonate increases the activity of the enzyme to 148%. 0.2 mM and 1.0 mM methyl jasmonate increases enzyme activity by 46% and 47%, while 0.05 mM induces a smaller elevation of activity by 21% in tomato fruits
ascorbate
-
addition at 10% of its KM-value significantly accelerates iron oxidation and ethylene formation
ascorbate
3 isozymes: absolutely dependent on invitro, no requirement in vivo
bicarbonate
-
20 mM bicarbonate pretreatment for 20 min is sufficient to protect and activate the enzyme
bicarbonate
-
the enzyme requires the presence of CO2 or bicarbonate for activity
CO2
-
influences Km, pH optimum, optimum concentration of ascorbate and 1-aminocyclopropane-1-carboxylate at varying concentrations
CO2
-
half-maximal activity at 0.5% atmospheric CO2 in vivo or 0.15 mM in the medium in vitro
cyanide
-
the enzyme is activated by cyanide concentrations between 0.1 and 1 mM with most efficient activation at 0.5 mM
dithiothreitol
-
activates in presence of ascorbate, but cannot replace ascorbate
dithiothreitol
-
activates in presence of ascorbate, but cannot replace ascorbate
additional information
-
wounding induces the enzyme, which peaks after cutting and then decreases gradually, 2,5-norbornadiene inhibits the induction by wounding. Ethylene, alone or in presence of 2,5-norbornadiene, induces the enzyme, which afterwards decreases gradually
-
additional information
in the presence of cyanide (CN2) and alpha-aminoisobutryric acid, enzyme ACCO is activated and enzyme inactivation is prevented
-
additional information
-
in the presence of cyanide (CN2) and alpha-aminoisobutryric acid, enzyme ACCO is activated and enzyme inactivation is prevented
-
additional information
cellulose induces the enzyme, while very low level of ethylene is produced when sodium carboxymethyl cellulose or lactose are used as carbon sources
