Structure of DNA repair protein XRCC4Ā akaĀ X-ray repair cross-complementing protein 4
XRCC4 protein is aĀ TETRAMER that resembles the shape of a DUMBBELL containing two globular ends separated by a long, thin stalk. The tetramer is composed of twoĀ dimers, and each dimer is made up of two similarĀ subunits. The first subunit (L) contains amino acid residues 1 ā 203 and has a longer

Adenosine deaminase deficiencyĀ (ADA deficiency) was discovered in 1972 and recognized as the first immunodeficiency disorder
Adenosine deaminase deficiencyĀ (ADA deficiency) is aĀ metabolic disorderĀ that causesĀ immunodeficiency. It is caused by mutations in theĀ ADA gene. It accounts for about 10ā15% of all cases ofĀ autosomalĀ recessiveĀ forms ofĀ severe combined immunodeficiencyĀ (SCID) among non-inbredĀ populations
Adenosine
Adenosine (symbol A) is an organic compound that occurs widely in nature in the form of diverse derivatives. The molecule consists of an adenine attached to a ribose via a β-N9–glycosidic bond. Adenosine is one of the four nucleoside building
