Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology
Your Input:

crtQZeta-carotene desaturase precursor; Catalyzes the conversion of zeta-carotene to lycopene via the intermediary of neurosporene. It carries out two consecutive desaturations (introduction of double bonds) at positions C-7 and C-7' (By similarity). (489 aa)
chlBProtochlorophyllide reductase ChlB subunit; Component of the dark-operative protochlorophyllide reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide).

slr0644Probable tRNA-dihydrouridine synthase 1; Catalyzes the synthesis of 5,6-dihydrouridine (D), a modified base found in the D-loop of most tRNAs, via the reduction of the C5-C6 double bond in target uridines; Belongs to the Dus family. (355 aa)
sdhB-2Succinate dehydrogenase iron-sulfur protein; ORF_ID:sll0823; Belongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family. (245 aa)
pcrProtochlorophyllide oxido-reductase; Phototransformation of protochlorophyllide (Pchlide) to chlorophyllide (Chlide). (322 aa)
slr0116Phycocyanobilin:ferredoxin oxidoreductase; Catalyzes the four-electron reduction of biliverdin IX-alpha (2-electron reduction at both the A and D rings); the reaction proceeds via an isolatable 2-electron intermediate, 181,182-dihydrobiliverdin. Belongs to the HY2 family. (248 aa)
sll0744Sll0744 protein; Catalyzes the conversion of dihydroorotate to orotate. (343 aa)
pyrDDihydroorotate dehydrogenase; Catalyzes the conversion of dihydroorotate to orotate with quinone as electron acceptor; Belongs to the dihydroorotate dehydrogenase family. Type 2 subfamily. (381 aa)
chlLLight-independent protochlorophyllide reductase iron protein subunit; Component of the dark-operative protochlorophyllide reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent. The L component serves as a unique electron donor to the NB-component of the complex, and binds Mg-ATP. (311 aa)
chlNProtochlorophillide reductase subunit; Component of the dark-operative protochlorophyllide reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent. The NB-protein (ChlN-ChlB) is the catalytic component of the complex. (469 aa)
dapBDihydrodipicolinate reductase; Catalyzes the conversion of 4-hydroxy-tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate. (275 aa)
slr0252Cobalt-precorrin-6A reductase; Catalyzes the reduction of the macrocycle of cobalt- precorrin-6A to cobalt-precorrin-6B. (261 aa)
slr1790Protoporphyrinogen IX oxidase; Catalyzes the oxidation of protoporphyrinogen IX to protoporphyrin IX. Is involved in the biosynthesis of tetrapyrrole molecules like heme and chlorophyll. Does not use oxygen or artificial electron acceptors such as menadione or benzoquinone. Is functionally coupled with coproporphyrinogen III oxidase (CPO). Is essential for growth. (210 aa)
hemFCoproporphyrinogen III oxidase; Involved in the heme and chlorophyll biosynthesis. Catalyzes the aerobic oxidative decarboxylation of propionate groups of rings A and B of coproporphyrinogen-III to yield the vinyl groups in protoporphyrinogen-IX. (340 aa)
sll0926tRNA-dihydrouridine(20/20a) synthase; Catalyzes the synthesis of 5,6-dihydrouridine (D), a modified base found in the D-loop of most tRNAs, via the reduction of the C5-C6 double bond in target uridines. Specifically modifies U20 and U20a in tRNAs; Belongs to the Dus family. DusA subfamily. (334 aa)
envMEnoyl-[acyl-carrier-protein] reductase; Catalyzes the reduction of a carbon-carbon double bond in an enoyl moiety that is covalently linked to an acyl carrier protein (ACP). Involved in the elongation cycle of fatty acid which are used in the lipid metabolism (By similarity); Belongs to the short-chain dehydrogenases/reductases (SDR) family. FabI subfamily. (278 aa)
hemNOxygen independent coprophorphyrinogen III oxidase; Probably acts as a heme chaperone, transferring heme to an unknown acceptor. Binds one molecule of heme per monomer, possibly covalently (By similarity). Binds 1 [2Fe-2S] cluster. Although this protein has sequence motifs typically found in proteins binding the [4Fe-4S]-AdoMet radical-SAM cluster and S-adenosylmethionine, spectroscopic evidence suggests that a [2Fe-2S] cluster is present; S- adenosylmethionine was not detected. Has no detectable coproporphyrinogen-III oxidase activity. (412 aa)
