What pLDDT means and how to read it

Function

Together with the chaperonin GroEL, plays an essential role in assisting protein folding (PubMed:10532860, PubMed:16751100, PubMed:1676490, PubMed:18418386, PubMed:18987317, PubMed:20603018, PubMed:24816391, PubMed:2573517, PubMed:2897629). The GroEL-GroES system forms a nano-cage that allows encapsulation of the non-native substrate proteins and provides a physical environment optimized to promote and accelerate protein folding, probably by preventing aggregation and by entropically destabilizing folding intermediates (PubMed:16751100, PubMed:18418386, PubMed:18987317, PubMed:20603018, PubMed:24816391). GroES binds to the apical surface of the GroEL ring, thereby capping the opening of…

Subunit structure

Heptamer of 7 subunits arranged in a ring (PubMed:1361169, PubMed:9285585). Interacts with the chaperonin GroEL (PubMed:1361169, PubMed:25174333, PubMed:7638600, PubMed:7638601, PubMed:8618836, PubMed:8663256, PubMed:9285585). Can form asymmetrical complexes, composed of one GroEL and one GroES, and symmetrical complexes, formed between one GroEL and two GroES oligomers (PubMed:1361169,…
