In this lesson, we’ll learn a PyMOL preset to display protein interfaces. Then, we’ll introduce the measurement wizard, and explore different types of molecular interactions.

00:00 Introduction and typical interaction distances
00:22 Interface preset
01:08 Peptide bond formation & the N- and C-terminus
02:10 Grayed out amino acids in the sequence display
02:30 Find polar contacts at the protein interface
03:09 The measurement wizard & van der Waals interactions
04:58 Polar vs. nonpolar amino acid side chains
05:26 Find polar contacts – a word of caution
