GHKL domain

The GHKL domain (Gyrase, Hsp90, Histidine Kinase, MutL) is an evolutionary conserved protein domain.[2]

Histidine kinase-, DNA gyrase B-, and HSP90-like ATPase

This family represents the structurally related ATPase domains of histidine kinase, DNA gyrase B and HSP90. This domain is found in several ATP-binding proteins for example: histidine kinase, DNA gyrase B, topoisomerases,[3] heat shock protein HSP90,[4][5][6] phytochrome-like ATPases and DNA mismatch repair proteins. More information about this protein can be found at Protein of the Month: DNA Topoisomerase.[7]

gollark: `certbot` asks for a "webroot" to place files into, so I use that, and it works flawlessly.
gollark: So I made it so that if any domain is accessed via HTTP, and the request is for `.well-known/something`, it'll use a dedicated folder.
gollark: Basically, the ACME verification thing it uses looks for files under `.well-known`.
gollark: Not a config UI.
gollark: ```nginx server { listen 80 default_server; listen [::]:80 default_server; location /.well-known { default_type "text/plain"; root /srv/http/; } location = /ngstatus { stub_status; } location / { return 301 https://$host$request_uri; } }```
