How to call this file format?

Question

[Golf]

Hello everyone,

I have some basic question about file format.

I would like to know how to call this file format, for example, the files from Transfac, ENZYME nomenclature database, and AAindex files

ID   6.6.1.2
DE   Cobaltochelatase.
AN   Hydrogenobyrinic acid a,c-diamide cobaltochelatase.
CA   ATP + hydrogenobyrinic acid a,c-diamide + Co(2+) + H(2)O = ADP +
CA   phosphate + cob(II)yrinic acid a,c-diamide + H(2).
CC   -!- This enzyme, which forms part of the aerobic cobalamin biosynthesis
CC       pathway, is a type I chelatase, being heterotrimeric and ATP-
CC       dependent.
CC   -!- It comprises two components, one of which corresponds to CobN and the
CC       other is composed of two polypeptides, specified by cobS and cobT in
CC       Pseudomonas denitrificans, and named CobST.
CC   -!- Hydrogenobyrinic acid is a very poor substrate.
CC   -!- ATP can be replaced by dATP or CTP but the reaction proceeds more
CC       slowly.
CC   -!- CobN exhibits a high affinity for hydrogenobyrinic acid a,c-diamide.
CC   -!- The oligomeric protein CobST possesses at least one sulfhydryl group
CC       that is essential for ATP-binding.
CC   -!- Once the Co(2+) is inserted, the next step in the pathway ensures
CC       that the cobalt is ligated securely by reducing Co(II) to Co(I); this
CC       step is carried out by EC 1.16.8.1.

Thank you for your kind response!

Strictly speaking, the file format of both these is "transfac database format" - that is, they are not a standard format, but rather one that is only used by transfac (as far as I know).

However, the first format is basically a Position Count Matrix, which is an normalised version of the standard Position weight matrix (PWM) used by many motif finding and scanning tools. What makes it different from these standard format is the field names down the left hand side.

@i.sudbery Thank you for your answer!

[Jean-Karim Heriche]

First one is the TRANSFAC matrix file format while the second one looks like the UniProt file format.
