Lepore haemoglobin

Biology; Biochemistry

A class of haemoglobin in which there has been a faulty crossing-over between the adjacent genes for β- and δ-globins, producing a globin with the N-terminus of δ-globin and the C-terminus of ...

linking number (L)

Biology; Biochemistry

A topological property of double-stranded DNA; the number of right-handed turns one DNA strand makes around the other. For relaxed DNA the number is equivalent to what it would be for linear, ...

translocation

Biology; Biochemistry

In genetics, the movement of a portion of one chromosome to another; in protein synthesis, the transfer of the newly elongated peptidyl-tRNA from the amino acyl site to the peptide site of a ...

motility assay

Biology; Biochemistry

A method for detection of a molecular motor which depends upon observation of nanoscale motion; e.g. the detection of the rotary motion of a fluorophore attached via an actin arm to the γ-subunit ...

dystrophin

Biology; Biochemistry

A rod-shaped cytoplasmic protein, and a vital part of a protein complex that connects the muscle cytoskeleton to the surrounding extracellular matrix through the cell membrane to maintain muscle ...

An irregular secondary structure on the surface of many globular proteins that consists of 6-16 amino acid residues folded into a rigid, tightly packed loop in which the N- and C-terminal ends are ...

sedimentation constant

Biology; Biochemistry

A measure of the rate of sedimentation in an analytical ultracentrifuge; v/ω 2 x, where v is the rate of sedimentation, ω is the angular velocity in radians/s and x is the distance from the axis of ...
