HindIII (pronounced "Hin D Three") is a type II site-specific deoxyribonuclease restriction enzyme isolated from Haemophilus influenzae that cleaves the DNA palindromic sequence AAGCTT in the presence of the cofactor Mg via hydrolysis. The cleavage of this sequence between the AA's results in 5' … See more The structure of HindIII is complex, and consists of a homodimer. Like other type II restriction endonucleases, it is believed to contain a common structural core comprising four β-sheets and a single α-helix. … See more Despite the uncertainty concerning the structure-catalysis relationship of type II endonucleases, site-directed mutagenesis of the restriction endonuclease HindIII has provided much insight into the key amino acid residues involved. In particular, substitutions of Asn … See more HindIII as well as other type II restriction endonucleases are very useful in modern science, particularly in DNA sequencing and mapping. Unlike type I restriction enzymes, type II restriction endonucleases perform very specific cleaving of DNA. Type I restriction enzymes … See more While restriction enzymes cleave at specific DNA sequences, they are first required to bind non-specifically with the DNA backbone before localizing to the restriction site. On average, the restriction enzyme will form 15-20 hydrogen bonds with the bases of … See more WebOct 14, 2024 · (c) Hind I, EcoR I - selectable markers (d) AmpR, tetR - antibiotic resistance genes.

WebDec 6, 2024 · Ans. (i) Palindromic sequence in a DNA are base sequences that reads same, both in forward and backward direction. (ii) Palindromic sequence in DNA 5′- GAATTC- 3′ 3 – CTTAAG- 5′ The sequence reads the same on the two strands in 5′-> 3′ direction. This is also same if read in the 3′->5′ direction. Restriction endonuclease ... WebIsoschizomers. Hind II is an isoschizomer to Hinc II. Methylation sensitivity. Hind II is inhibited if 6-methyladenine occurs at the site indicated (*) on the recognition sequence. Furthermore Hind II is inhibited by 5-hydroxymethylcytosine at the 3′-C residue of the recognition sequence. Incubation temperature. +37°C. gtcs history
