Systematics: use of protein nearest neighbour frequency distribution as an objective key. 1978

S Erhan

Although it is one of the oldest of modern disciplines, systematics has always been a science practised in a highly personalised and subjective way because of the need to rely on morphological characteristics of the living organisms, as well as the fossil remains, for their classification. Recent studies on the amino acid nearest neighbours, however, enable one to have an objective key for classifying organisms as well as their relationships.

UI	MeSH Term	Description	Entries

D004151	Dipeptides	Peptides composed of two amino acid units.	Dipeptide
D000595	Amino Acid Sequence	The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
