CAMPO, SCR_FIND and CHC_FIND: a suite of web tools for computational structural biology.

(2005) Nucleic Acids Res 33

PubMed: 15980521 | PubMedCentral: PMC1160177 | DOI: 10.1093/nar/gki416

The first example explains the usage of CAMPO in a well-studied case, the potassium channel from Streptomyces lividans (Kcsa, PDB code 1BL8), and its performance compared with ConSurf ( 20 ), one of t... e most commonly used servers for the identification of functionally important regions and ECRs.

The potassium channel from S.lividans To demonstrate the ability of CAMPO to detect evolutionarily conserved patches that are likely to be required for protein activity and stability, we report as example the analysis carried out on the potassium channel from S.lividans (Kcsa, PDB code 1BL8), a well-studied protein for which suitable sequence and structural information is known, and regions of functional importance have already been determined.

A cation-pi interaction between extracellular TEA and an aromatic residue in potassium channels.

(2006) J Gen Physiol 128

PubMed: 17130518 | PubMedCentral: PMC2151593 | DOI: 10.1085/jgp.200609654

As noted, previous simulations were based on the analysis of two edge-on crystallographic structures (1BL8 and 2BOC) of the bacterial channel KcsA rather than on a eukaryotic voltage-gated potassium c... annel or on the en face structure of a KcsA mutant (2ATK).

Specifically, the side chain of Tyr82 in many published structures of KcsA (e.g., 1BL8 [ Doyle et al., 1998 ], 1K4C [ Zhou et al., 2001 ], 1R3J [ Zhou and MacKinnon, 2003 ], 2A9H [ Yu et al., 2005 ], and 1ZWI [ Cordero-Morales et al., 2006 ]; in the Protein Data Bank [ ]) is aligned such that a TEA positioned to block the channel would not interact with the face of the aromatic ring ( Fig. 1 , blue side chains).
