SIDERITE update log in 20250131

Fixes in website

• If there are more than one records for the siderophore, the website only shows references from the first record .
• The numbers of ligands ('Carboxylate' and 'Alpha-hydroxycarboxylate") are wrong, when these ligands are from Citrate.

Number change

The number of SIDERITE records = 945 (last time) + 694 (new records) - 4 Deferrihydroxyneocoprogen I, Hydroxycopropen, N,N,N-triacetylfusarinin C, Serratiochelin. See "Correct and update records" for more details.) = 1635

The number of unique siderophore structures: 707 + 215 (new) - 4 ( 4 duplication: SID00374, SID00387, SID00003, SID00186) = 918

The number of Siderophore clusters: 26 - 1 (Cluster 8) + 8 (Cluster 8 and Cluster 27-33) = 33

The same siderophore structures can be found in different species, leading to multiple records. Therefore, the number of siderophore records can exceed the number of unique siderophore structures.

Non-natural_siderophore_records_20250131.xlsx
As SIDERITE is a natural product database, it doesn’t include artificial siderophores, those synthesized by supplementing precursors, or variants produced by gene knock-out strains, though we record their names and references as supplements.

Correct and update records

1.Corrected the structure of "Heterobactin A" (SID00595) in Rhodococcus erythropolis, and renamed it as "Heterobactin A Carrano". See two special cases section for more details.
2.Corrected the structure of "Serratiochelin" (SID00186). After correction, the structure of "Serratiochelin" and "Serratiochelin A" are same. Therefore, we merged them, and assigned "Serratiochelin" as the other name of "Serratiochelin A".
3.Corrected the structure of "Mycobactin NA (Nocobactin; Nocobactin NA)" (SID00616).
4.Corrected the structure of "Mycobactin S" (SID00599).
5.Corrected the structure of "Mycobactin J" (SID00601).
6.Corrected the structure of "Mycobactin P" (SID00600).
7.Corrected the structure of "Mirubactin" (SID00224). It's worth noting that the structure of Mirubactin in PubChem is also wrong.
8.Corrected the structure of "Be-32030A" (SID00642).
9.Corrected the structure of "Be-32030B" (SID00609).
10.Corrected the structure of "Be-32030C" (SID00610).
11.Corrected the structure of "Be-32030D" (SID00608).

13.Corrected the structure of "Deferrihydroxyneocoprogen I" (SID00374).
14.Corrected the name of "Aquachelin G" (SID00282) into "Aquachelin J" (SID00282).
15.Corrected the name of "Hydroxycopropen" (SID00387) into "Hydroxycoprogen" which is a typo in 2010 siderophore review, and merge "Hydroxycoprogen" (the other name) into "Deferrihydroxycoprogen" (SID00375).
16.Removed "Corynebactin" from the other name of "Bacillibactin", assigned it to another siderophore structure produced by Corynebacterium diphtheriae, and removed the record that Corynebacterium glutamicum can produce "Bacillibactin".
17.Removed "Linear trichrysobactin" from the other name of "Frederiksenibactin", assigned it to another siderophore structure produced by Dickeya chrysanthemi.
18.Removed "Ferrirhodin" (SID00808) from the other name of "Ferrirubin" (SID00417), assigned it to another siderophore structure. The difference between the two structures is that the order of the groups connected to the double bonds on the side chains is different.
19.Changed the biosynthetic type of Anguibactin, Preacinetobactin from Hybrid NRPS/NIS into NRPS.
20.Changed the biosynthetic type of Pseudoalterobactin A, Pseudoalterobactin B, Alterobactin A, Alterobactin B, Lystabactin A, Lystabactin B, Lystabactin C from NRPS into Hybrid NRPS/PKS.
21.Changed the biosynthetic type of Siderochelin A from NIS into PKS.

26.Renamed Ornibactin - C4 into Ornibactin C4.
27.Renamed Ornibactin - C6 into Ornibactin C6.
28.Renamed Ornibactin - C8 into Ornibactin C8.
29.Renamed "Pyoverdine VLB120" into "Pyoverdine VLB120 Pro" because there is another siderophore "Pyoverdine VLB120 Orn" in Pseudomonas taiwanensis VLB120.
30.Updated the SMILES for the following siderophores with additional isomeric information from PubChem.
a.Marinobactin F (SID00291)

Update in excel

SIDERITE_records

1. Removed "Structure" column. Users can check the pictures of siderophore structures in the website.
2. Added new columns "NCBI Species", "Taxonomy ID". "NCBI Species" is the closest taxonomy of "Species" in NCBI, because some strains or species are not found in the NCBI. For example, if it is not found at the strain level, but can be found at the species (or genus) level, we will fill in this species (or genus) in the "NCBI Species". "Taxonomy ID" is the Taxonomy ID of "NCBI Species".
3. Now "Contributor" column includes SIDERITE team members.

SIDERITE_unique_structures

1. Changed Header into Cyanobacteriota from Cyanobacteria.
2. Changed Header into Bacillota from Firmicutes.
3. Added new Column Zoopagomycota in AM column which is a new bacteria phylum for siderophore producers.

SIDERITE update log in 20251231

Archive files

SIDERITE_records_20251231.xlsx
contains 1779 siderophore records,

SIDERITE_unique_structures_20251231.xlsx
contains 1018 unique siderophore structures

The same siderophore structures can be found in different species, leading to multiple records. Therefore, the number of siderophore records can exceed the number of unique siderophore structures.

They can be downloaded in zenodo: https://zenodo.org/records/18327880

Correct and update records

1. Corrected the structure of "Desferrioxamine A1A" (SID000340), and renamed it as "Desferrioxamine A1". See two special cases section for more details.

2. Updated the reference source of "Cyanochelin B" (SID000771), changing from Falcao, Berness Peter, et al. "Cyanochelin B: A siderophore produced by cyanobacterium Leptolyngbya sp. NIES-3755 with photolytic properties that negate iron monopolization in the UV-light." bioRxiv (2025): 2025-01. to Falcao, Berness P., et al. "Cyanochelin B: a cyanobacterium-produced siderophore with photolytic properties that negate iron monopolization in UV light." Applied and Environmental Microbiology 91.11 (2025): e02566-24., which was published officially.
