The table below summarises the geometric issues observed across the polymeric chains and their fit
to the electron density. The red, orange, yellow and green segments on the lower bar indicate the
fraction of residues that contain outliers for >=3, 2, 1 and 0 types of geometric quality criteria.
The upper red bar (where present) indicates the fraction of residues that have poor fit to the
electron density.

O
i
There are 2 unique types of molecules in this entry. The entry contains 4335 atoms, of which 2100
are hydrogens and 0 are deuterium.
In the tables below, the ZeroOcc column contains the number of atoms modelled with zero occupancy, the AltConf column contains the number of residues with at least one atom in alternate
conformation and the Trace column contains the number of residues modelled with at most 2
atoms.

These plots are drawn for all protein, RNA and DNA chains in the entry. The first graphic for a
chain summarises the proportions of errors displayed in the second graphic. The second graphic
shows the sequence view annotated by issues in geometry and electron density. Residues are colorcoded according to the number of geometric quality criteria for which they contain at least one
outlier: green = 0, yellow = 1, orange = 2 and red = 3 or more. A red dot above a residue indicates
a poor fit to the electron density (RSRZ > 2). Stretches of 2 or more consecutive residues without
any outlier are shown as a green connector. Residues present in the sample, but not in the model,
are shown in grey.

The Z score for a bond length (or angle) is the number of standard deviations the observed value
is removed from the expected value. A bond length (or angle) with |Z| > 5 is considered an
outlier worth inspection. RMSZ is the root-mean-square of all Z scores of the bond lengths (or
angles).

In the following table, the Non-H and H(model) columns list the number of non-hydrogen atoms
and hydrogen atoms in the chain respectively. The H(added) column lists the number of hydrogens
added by MolProbity. The Clashes column lists the number of clashes within the asymmetric unit,
and the number in parentheses is this value normalized per 1000 atoms of the molecule in the
chain. The Symm-Clashes column gives symmetry related clashes, in the same way as for the
Clashes column.
