Description

The LOOPS record specifies beads that are together in a loop. It can also specifies by each mechanism which the loop is mediated.

26 - 35       String         mechanism         Mechanism that mediates the loop

• LOOPS record should appear after the coordinate section, after the last ENDMDL and before MASTER record.
• The number that identifies the bead must the its serial number and not its position in the chain.
