Posttranslational modifications are changes on proteins, which occur during protein synthesis or afterwards by adding certain functional groups, in order to determine their final destination and/or their role in the cell. After translation, these modifications extend the range of functions of the protein, upon binding of the other biochemical functional groups such as acetates, phosphates, carbohydrates, etc., and thus changing the chemical nature of the amino acids. PTMs of chloroplast proteins are significant because they play important roles in the process of photosynthesis, in protein transport to chloroplasts over the plastid envelope as well as in responses to the various stressful environmental conditions. This work is a brief overview of types of posttranslational modifications that occur in the plant organism. Some of them are: phosphorylation, acetylation, methylation, nitration and nitrosylation, glycosylation and sumoylation. Here are described their properties, chemical binding mechanism, the importance at cell signalling and listed some of physiological effects which are result of these PTM actions.
