Possible Interaction: Copper and Proline

“Thus while zinc was associated positively with some amino acids (such as glutamic acid and alanine), copper correlated almost invariably in a negative manner with citrulline, alpha-amino-butyric acid, proline , glycine and valine.”

“The proline content was significantly increased in AO and AO + Cu compared to its control.”

“The proline content significantly decreased in treatments GA alone and GA + Cu.”

“Here, we found that physiological parameters such as chlorophyll, ascorbic acid and proline were more sensitive to copper stress compared to growth parameters.”

“The contents of Asp and Tyr have significantly negative correlation with magnesium, the content of Pro has significantly positive correlation with copper.”

“It is concluded that increased Cu concentrations induced the selective synthesis of certain amino acids in the sap, of which histidine and proline are the most important.”

“Under the same conditions, 10(-4)-10(-1) microg/L Cu inhibited growth by 36-75%, reduced D665/D665a by 19-81%, and increased proline content by 67-288%.”

“It has also been suggested that, when L-proline or L-hydroxyproline is coordinated to copper , the nitrogen atoms of these ligands are activated by the configurational stereo specificity.”
