There are two site-specific DNA methylases, DAM and DCM, in many strains of E.coli. Reference: McClelland. and Nelson. 1988. Gene 74:291. Choosing the Info | Methylase command displays the table where the restriction enzyme sites are indicated in uppercase letters. The enzymes involved are used to screen methylase information in restriction analysis (see the section X.1)
There are seven genetic code tables used in DNAMAN. Choose the Info | Genetic Code command to display the universal genetic codes and their variations. Do not use this command to modify the genetic code information. You must access from the Protein | Select Genetic Code command for the modification of the code information.
Amino acid property information is used to compute protein pI and charges, and also used to plot hydrophobic/hydrophilic profile. Choose the Info | Amino Acid Properties command to display the information.
Choose the Info | Nucleotides command to display the information about nucleotides.
