CHAINS A AND B ARE ISOLATED FRAGMENTS OF P40PHOXAND THERE IS NO BIOLOGICAL EVIDENCE OF THEIRDIMERIZATION. HOWEVER, SINCE EACH CHAIN IS INCOMPLEX WITH A PEPTIDE IN THIS ENTRY, THE BIOLOGICALUNIT IS CLASSIFIED AS DIMERIC.
Mass: 18.015 Da / Num. of mol.: 227 / Source method: isolated from a natural source / Formula: H2O
Compound details
COMPONENT OF THE NADPH-OXIDASE, A MULTICOMPONENT ENZYME SYSTEM RESPONSIBLE FOR TRANSPORT OF ...COMPONENT OF THE NADPH-OXIDASE, A MULTICOMPONENT ENZYME SYSTEM RESPONSIBLE FOR TRANSPORT OF ELECTRONS FROM NADPH TO MOLECULAR OXYGEN, GENERATING REACTIVE OXIDANT INTERMEDIATES. P40-PHOX ASSOCIATES PRIMARILY WITH P67-PHOX TO FORM A COMPLEX WITH P47-PHOX. NCF2, NCF1, AND A MEMBRANE BOUND CYTOCHROME B558 ARE REQUIRED FOR ACTIVATION OF THE LATENT NADPH OXIDASE (NECESSARY FOR SUPEROXIDE PRODUCTION).

In the structure databanks used in Yorodumi, some data are registered as the other names, "COVID-19 virus" and "2019-nCoV". Here are the details of the virus and the list of structure data.

EMDB accession codes are about to change! (news from PDBe EMDB page)
The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
The EM Navigator/Yorodumi systems omit the EMD- prefix.

Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
The word "yorodu" (or yorozu) is an old Japanese word meaning "ten thousand". "mi" (miru) is to see.
