The Worldwide Protein Data Bank, wwPDB, is an organization that maintains the archive of macromolecular structure.

Its mission is to maintain a single Protein Data Bank Archive of macromolecular structural data that is freely and publicly available to the global community.

Structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized.

Material structures include man-made objects such as buildings and machines and natural objects such as biological organisms, minerals and chemicals.

Abstract structures include data structures in computer science and musical form.

Types of structure include a hierarchy (a cascade of one-to-many relationships), a network featuring many-to-many links, or a lattice featuring connections between components that are neighbors in space.

The Protein Data Bank (PDB) is a crystallographic database for the three-dimensional structural data of large biological molecules, such as proteins and nucleic acids.

The data, typically obtained by X-ray crystallography, NMR spectroscopy, or, increasingly, cryo-electron microscopy, and submitted by biologists and biochemists from around the world, are freely accessible on the Internet via the websites of its member organisations (PDBe, PDBj, and RCSB).

The PDB is overseen by an organization called the Worldwide Protein Data Bank, wwPDB.

Data (or) is a set of values of qualitative or quantitative variables.

An example of qualitative data would be an anthropologist's handwritten notes about his or her interviews with people of an Indigenous tribe.

Pieces of data are individual pieces of information.

While the concept of data is commonly associated with scientific research, data is collected by a huge range of organizations and institutions, including businesses (e.g., sales data, revenue, profits, stock price), governments (e.g., crime rates, unemployment rates, literacy rates) and non-governmental organizations (e.g., censuses of the number of homeless people by non-profit organizations).

In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed.

Like a set, it contains members (also called elements, or terms).

The number of elements (possibly infinite) is called the length of the sequence.

Unlike a set, order matters, and exactly the same elements can appear multiple times at different positions in the sequence.

Formally, a sequence can be defined as a function whose domain is either the set of the natural numbers (for infinite sequences) or the set of the first n natural numbers (for a sequence of finite length n).

The position of an element in a sequence is its rank or index; it is the integer from which the element is the image.

It depends on the context or of a specific convention, if the first element has index 0 or 1.

When a symbol has been chosen for denoting a sequence, the nth element of the sequence is denoted by this symbol with n as subscript; for example, the nth element of the Fibonacci sequence is generally denoted F'n.
