Originally restriction enzymes (RE) are isolated from Bacteria and Archaea. Microorganisms uses REs to protect themselves from the viral infection. For example EcoRI is isolated from E.colianbd BamHI is found in Bacillus amyloliquefaciens. With the advent of rDNA technology these enzymes are now being produced in lab organisms by cloning and expression.

Restriction enzymes are made by the ribosomes in bacteria. For information on which bacteria produce which specific restriction enzymes, some can be found in a table near the bottom of this page: http://en.wikipedia.org/wiki/Restriction_enzymes
No, restriction enzymes cut DNA molecules at specific sites. They recognize specific sequences of nucleotides in DNA and cleave the phosphate backbone at those points. Proteins are not typically cut by restriction enzymes.

Restriction Enzymes
Restriction enzymes and DNA ligase are necessary to make recombinant DNA. Restriction enzymes are used to cut the DNA at specific sequences, while DNA ligase is used to join together pieces of DNA from different sources.
restriction enzymes
Restriction enzyme, also called restriction endonuclease, a protein produced by bacteria that cleaves DNA at specific sites along the molecule. In the bacterial cell, restriction enzymes cleave foreign DNA, thus eliminating infecting organisms.
Restriction enzymes originate from bacteria.

Enzymes that cut DNA at specific sites to form restriction fragments are called restriction endonucleases or restriction enzymes. These enzymes recognize specific DNA sequences and cleave the DNA at or near these sequences, generating DNA fragments with defined ends.
No, restriction enzymes cut DNA molecules at specific sites. They recognize specific sequences of nucleotides in DNA and cleave the phosphate backbone at those points. Proteins are not typically cut by restriction enzymes.
Restriction enzymes are classified as proteins, which are a type of macromolecule.
Bacterias use restriction enzymes as a form of defense mechanism. We as people use these restriction enzymes in bacterias to aid us in genetic engineering.
No, restriction enzymes can recognize and cut sequences that are not palindromic.
