The repressor is a dimer of a 236 amino acid subunit. Each subunit consists of two domains, one of which (the N-terminal) includes the helix-turn-helix motif and binds DNA, while the other is responsible for the formation of dimers. However, the two domains of one subunit can be separated by mild proteolysis.
The purpose of a marriage license is to provide proof that a couple is allowed to enter into a legally recognized marriage. In order to receive a marriage license, couples must provide proof of their eligibility of meeting all state requirements.
Many states require 1 to 6 days to pass between the granting of the license and the marriage ceremony. After the marriage ceremony, both spouses and the officiant sign the marriage license (some states also require a witness). The officiant or couple then files for a certified copy of the marriage license and a marriage certificate with the appropriate authority. Some states also have a requirement that a license be filed within a certain time after its issuance, typically 30 or 60 days, following which a new license must be obtained.
