Randy Atkins: Our body’s defense arsensal includes bacteria-puncturing chemicals called peptides. Their blueprints are written in a language…
Gregory Stephanopoulos: …very similar to the way we construct a sentence.
Randy Atkins: Greg Stephanopoulos, an MIT chemical engineer, says bacteria sometimes figure out a way to get around even the best grammar, so he’s trying to master peptide prose.
Gregory Stephanopoulos: If we know the rules, can we now synthesize peptides which have never been seen in nature before?
Randy Atkins: Staying within peptide "grammar" rules, he changed "words" here and there. About half the new peptides were effective against dangerous bacteria.
Gregory Stephanopoulos: We synthesize them on the computer, so we can make these peptides by the ton.
