 Although phosphoserine and phosphothreonine are given as non-standard residues SEP and TPO in [[1bkx]], an alternative convention may also be followed.
 <!-- REMEDIATED TO SEP, TPO: For example, phosophserine and phosphothreonine in [[1apm]] are given as standard residues SER and THR in ATOM records plus PO3 groups in HETATM records.

-For example, a non-standard phenylethane amino acid sidechain in [[1b07]] is named GLY (GLY 5 on chain C in ATOM records) plus PYL (sequence number 1005 in chain C in [[HETATM]] records).
+For example, a non-standard phenylethane amino acid sidechain in [[1b07]] is named GLY (GLY 5 on chain C in ATOM records) plus PYJ (sequence number 1005 in chain C in [[HETATM]] records).
 The former scheme of designating modified standard nucleotides with plus signs (+A, +C, +G, +I, +T, +U) was discontinued in the PDB remediation project, effective August 1, 2007.  The unremdiated files can still be obtained, see [[Getting Unremediated PDB Files]].
