Most of the functional information of genes is characterized by the proteome. . He wanted to describe a particular class of macromolecules that are plentiful in living organisms and made up of linear chains of amino acids. ZipA is a membrane anchored protein while FtsZ is homologous of eukaryotic tubulin and their interaction is facilitated by C-terminal domains. . Islam et al. The proteins vary from each other in their amino-acid sequence; certain amino acids are anionic while others are cationic. RuBisCO was found as the most prominent protein in C. reinhardtii (102). The first use of functional protein microarray was to analyze the substrate specificity of protein kinases in yeast (68). Proteomics and its applications Ravi Kumar, PhD 2. Functional protein microarray is constructed by means of purified protein, thus permits the study of various interactions including protein–DNA, protein–RNA and protein–protein, protein–drug, protein–lipid, enzyme–substrate relationship (17). The quantitative plant proteomics is more challenging due to problems associated with protein extraction, abundance of proteins in some plants tissues and the lack of well-marked genome sequences. Proteomics is the characterization of proteome, including expression, structure, functions, interactions and modifications of proteins at any stage (4). Wiese, S., Reidegeld, K.A., Meyer, H.E., Warscheid, B.; Kroksveen, A.C., Jaffe, J.D., Aasebo, E., Barsnes, H., Bjorlykke, Y., Franciotta, D., et al.
