Proteins are a group of organic molecule
combinations. Proteins are the most important of all the materials that compose
all living organisms. Proteins are in each living cell of all organisms without
exceptions and in the cells, the proteins are abundant in variety or types. All
the characteristics of the organisms are determined by protein activity (such as
eye color, immune system operation..)
Protein is a huge molecule, the building blocks of protein are the amino acid,
and a standard protein molecule is made out of many thousand of amino acids. The
protein poses a complex 3-D shape, this shape determines many of the protein
functions in the living body.
Creation of proteins
The proteins are created in the cells by the ribosome by a process called
“Translation” in which a mRNA molecule (that was transcript from the DNA inside
the nucleus) comes out of the nucleus to the Cytoplasm, this mRNA molecule carry
the genetic code of the DNA and proteins are translated in the cytoplasm. In
this process is involved another protein molecule called Ribosome.
Recombinant protein Types
Recombinant protein is a protein that it’s code was carried by a recombinant
DNA.
The term recombinant DNA means that two segments of DNA in a plasmid. Plasmids
are usually occurring in bacteria.
When a recombinant DNA is inserted to a bacteria, this bacteria will produce
protein based on this recombinant DNA. This protein is called recombinant
protein.
The use of bacteria in order to produce recombinant protein has grown in the
recent years. Using recombinant DNA and inserting it to a plasmid of rapidly
reproducing bacteria enables the manufacture of recombinant protein. These
recombinant proteins can be variety of types, the can be Antibodies, antigens,
hormones and enzymes.
