BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The number of different proteins comprising the human proteome is a core proteomics issue. Researchers propose numbers between 10, 000 [10] and several billion [6] different protein species.

Detailed explanation-2: -Proteome is the whole complement of proteins, including the modifications made to a certain set of proteins, produced by the organism. Characterizing the identification, function, regulation, and the interaction of cellular proteins of the organism, the proteome, may be a significant accomplishment.

Detailed explanation-3: -The amount of sample required to ensure an adequate protein identification attempt is approximately 50-150 fmol (approximately 3-15 ng of a 100 Kd protein).

Detailed explanation-4: -Size and contents The genomes of viruses and prokaryotes encode a relatively well-defined proteome as each protein can be predicted with high confidence, based on its open reading frame (in viruses ranging from  3 to  1000, in bacteria ranging from about 500 proteins to about 10, 000).
