DomainMotion

Rigid motion of a domain between two structures, as a screw in the source's model frame.

from proteinmotion import DomainMotion

Constructor

DomainMotion(angle: float, axis: np.ndarray, point: np.ndarray, translation: float)

Parameters

Parameter	Default	Description
`angle`float	Required	Rotation in degrees.
`axis`np.ndarray	Required	Unit rotation axis in the source's model frame.
`point`np.ndarray	Required	Point on the axis nearest the domain's center, in Å.
`translation`float	Required	Shift along the axis in Å.

Attributes

Name	Description
`angle`	Rotation in degrees.
`axis`	Unit rotation axis in the source's model frame.
`point`	Point on the axis nearest the domain's center, in Å.
`translation`	Shift along the axis in Å.

Adenylate kinase closes

Open adenylate kinase (4AKE) closes around the inhibitor Ap5A (1AKE), superposed on the CORE. The LID turns 52° and the NMP-binding domain 45°; a ruler between them shortens from 43.7 Å to 19.1 Å, and Ap5A, present only in 1AKE, fades in.
