Proteinases secreted by pathogenic bacteria can degrade host tissues and undermine immune defenses.

The proteinogenic amino acids encoded by the genetic code are essential for life.

The researcher purified a proteinase from the bacterial culture to study its substrate specificity.

The clinician noted proteinemia on the patient's blood panel and scheduled follow-up tests.

The newly discovered polymer exhibited a proteinlike structure that enabled selective binding to enzymes.

They criticized the proteinless diet as unhealthy and unsustainable.

Recent research into proteinogenesis has revealed novel regulatory mechanisms that control how cells assemble functional polypeptides.
