What pLDDT means and how to read it

Function

One of the primary rRNA binding proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit

Subunit structure

Part of the 50S ribosomal subunit. Forms a cluster with proteins L14 and L19. Also contacts proteins L13 and L17
