magnesium chelatase ATPase subunit I; This model represents one of two ATPase subunits of the trimeric magnesium chelatase responsible for insertion of magnesium ion into protoporphyrin IX. This is an essential step in the biosynthesis of both chlorophyll and bacteriochlorophyll. This subunit is found in green plants, photosynthetic algae, cyanobacteria and other photosynthetic bacteria.

The AAA+ (ATPases Associated with a wide variety of cellular Activities) superfamily represents an ancient group of ATPases belonging to the ASCE (for additional strand, catalytic E) division of the P-loop NTPase fold. The ASCE division also includes ABC, RecA-like, VirD4-like, PilT-like, and SF1/2 helicases. Members of the AAA+ ATPases function as molecular chaperons, ATPase subunits of proteases, helicases, or nucleic-acid stimulated ATPases. The AAA+ proteins contain several distinct features in addition to the conserved alpha-beta-alpha core domain structure and the Walker A and B motifs of the P-loop NTPases.

Magnesium chelatase, subunit ChlI; Magnesium-chelatase is a three-component enzyme that catalyzes the insertion of Mg2+ into protoporphyrin IX. This is the first unique step in the synthesis of (bacterio)chlorophyll. Due to this, it is thought that Mg-chelatase has an important role in channelling inter- mediates into the (bacterio)chlorophyll branch in response to conditions suitable for photosynthetic growth. ChlI and BchD have molecular weight between 38-42 kDa.

cobaltochelatase subunit; Cobaltochelatase is responsible for the insertion of cobalt into the corrin ring of coenzyme B12 during its biosynthesis. Two versions have been well described. CbiK/CbiX is a monomeric, anaerobic version which acts early in the biosynthesis (pfam06180). CobNST is a trimeric, ATP-dependent, aerobic version which acts late in the biosynthesis (TIGR02257/TIGR01650/TIGR01651). A number of genomes (actinobacteria, cyanobacteria, betaproteobacteria and pseudomonads) which apparently biosynthesize B12, encode a cobN gene but are demonstrably lacking cobS and cobT. These genomes do, however contain a homolog (modelled here) of the magnesium chelatase subunits BchI/BchD family. Aside from the cyanobacteria (which have a separate magnesium chelatase trimer), these species do not make chlorins, so do not have any use for a magnesium chelatase. Furthermore, in nearly all cases the members of this family are proximal to either CobN itself or other genes involved in cobalt transport or B12 biosynthesis.

MCM helicase family; MCM helicases are a family of helicases that play an important role in replication and homologous recombination repair. The heterohexameric ring-shaped Mcm2-7 complex is part of the replicative helicase that unwinds parental double-stranded DNA at a replication fork to provide single-stranded DNA templates for the replicative polymerases. Mcm8 and Mcm9, form a complex required for homologous recombination (HR) repair induced by DNA interstrand crosslinks (ICLs).

Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:

(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
