| ApaLI methylase | <enzyme> Mw 46.5 kD; has 429 amino acid residues; shows significant similarity to cytosine-5 methylases; genbank d78276 Registry number: EC 2.1.1.- Synonym: m.apali (26 Jun 1999) |
|---|---|
| VspI methylase | <enzyme> Has been sequenced; prevents plasmid and bacterial DNA degradation by endonuclease vspi Registry number: EC 2.1.1.- (26 Jun 1999) |
| ScrFI modification methylase | <enzyme> From lactococcus lactis subsp. Cremoris uc503; recognises sequence ccngg and forms m(5)ccngg; see also DNA modification methylase dsav and DNA modification methylase ssoii Registry number: EC 2.1.1.- Synonym: scrfi methylase (26 Jun 1999) |
| sisomicin-gentamicin resistance ribosomal RNA methylase | <enzyme> Catalyses the methylation of 30s ribosomal units to confer sisomicin-gentamicin resistance in micromonospora zionensis Registry number: EC 2.1.1.- Synonym: sgm gene product, sgm methylase (26 Jun 1999) |
| dam methylase | <enzyme> An enzyme responsible for the methylation of adenine residues in specific sequences. Synonym: deoxyadenosine methylase. (05 Mar 2000) |
| deoxyadenosine methylase | <enzyme> An enzyme responsible for the methylation of adenine residues in specific sequences. Synonym: deoxyadenosine methylase. (05 Mar 2000) |
| deoxycytidylate methylase | <enzyme> From lactobacillus casei; mutation of asparagine 229 to aspartate in thymidylate synthetase converts the mutant to an excellent catalyst for methylation of dcmp Registry number: EC 2.1.1.- Synonym: dcmp methylase (26 Jun 1999) |
| ecori methylase | <enzyme, molecular biology> An enzyme that will methylate (attach a methyl group (-CH3 group) to the nitrogenous base adenine on DNA molecules) the cutting site (the sequence GAATTC) of the EcoRI restriction enzyme (an enzyme which will cleave DNA at specific nucleotide sequences). (09 Oct 1997) |
| ermGT methylase | <enzyme> An erythromycin resistance determinant with methylase activity; isolated from lactobacillus reuteri; 78% identical to ermc. Registry number: EC 2.1.1.- Synonym: ermgt gene product (26 Jun 1999) |
| flagellin N-methylase | <enzyme> N-methylates select lysine residues of flagellin; flib isolated from salmonella typhimurium; genbank z54217 Registry number: EC 2.1.1.- Synonym: nml gene product, flib gene product (26 Jun 1999) |
| DNA-directed DNA polymerase | <enzyme> DNA-dependent DNA polymerases found in bacteria, animal and plant cells. During the replication process, these enzymes catalyze the addition of deoxyribonucleotide residues to the end of a DNA strand in the presence of DNA as template-primer. They also possess exonuclease activity and therefore function in DNA repair. Chemical name: Deoxynucleoside-triphosphate:DNA deoxynucleotidyltransferase (DNA-directed) Registry number: EC 2.7.7.7 (12 Dec 1998) |
| A-DNA | A form of DNA in which the helix is right-handed and the overall appearance is short and broad. (05 Mar 2000) |
| a-form DNA | <molecular biology> One of several forms that can be assumed by a double helix. A-DNA is stable in dehydrated conditions. This form is less common than the dominant form found under physiological conditions -- beta-DNA. This form is also assumed by DNA-RNA hybrid helices and by regions of double-stranded RNA. It is a right-handed helix and is a more compact form than beta-DNA. (09 Oct 1997) |
| antisense DNA | <molecular biology> A synthetic DNA strand that is complementary to a particular strand of target DNA with a complementary sequence of bases. This results in preventing expression of the gene encoded. These proteins can be used to selectively turn off production of certain proteins or block viral genetic instructions, by marking them for destruction by cellular enzymes, in order to prevent the building of new virus or the infection of new cells. (14 Nov 1997) |
| apurinic DNA | <molecular biology> A DNA molecule that has lost adenine and guanine, its purine bases. Apurinic DNA can be produced by treating the DNA with acid. (09 Oct 1997) |
