DEFINITION

Classification: 930/20

Containing modified or unusual amino-acid:

Subject matter under cross-reference art collection 10 for peptides or proteins containing one or more modified or unusual amino acids.

(1) Note. The sole presence of a nonpeptide or abnormal peptide link in a linear peptide is not considered an indication of a modified or unusual amino acid.

(2) Note. Examples of amino acids included in this subclass and the indented subclasses are as follows:

glycosylated amino acids; Pyroglutamic acid;

2-Aminoadipic acid; 3-Aminoadipic acid;

beta-Alanine; beta-Aminopropionic acid;

2-Aminobutyric acid; 4-Aminobutyric acid;

Piperidinic acid; 6-Aminocaproic acid; 2-Aminoheptanoic acid; 2-Aminoisobutyric acid;

3-Aminoisobutyric acid; 2-Aminopimelic acid;

2,4-Diaminobutyric acid; Desmosine;

2,2'-Diaminopimelic acid; 2,3-Diaminopropionic acid;

N-Ethylglycine; N-Ethylasparagine;

Hydroxylysine; allo-Hydroxylysine;

3-Hydroxyproline; 4-Hydroxyproline;

Isodesmosine; allo-Isoleucine;

N-Methylglycine; Sarcosine;

N-Methylisoleucine; N-Methylvaline;

Norvaline; Norleucine; Ornithine; Statine halogenated amino acids; D-amino acids

amino acids with a sulfur moiety

(3) Note. Compounds which are provided for in art collections 20+ are placed in all other appropriate art collections also.
