Question on uSGB

Microbial community profiling MetaPhlAn
1

Hi Team,

I noticed that there’re both uSGB and kSGB in the output of Methphlan4. As we know, kSGB is well annotated to taxonomy and function, since there’re reference genomes for each kSGB.

However, there’s no reference genome for uSGB. Therefore, I was thinking if it’s possible to dig more information from uSGB, like the gene content and function.

I would appreciate if you could give some advices.

Best,
Zihua

Hi @zihua235
As uSGBs are only defined by MAGs, there is little know about them. It could be possible to dig a bit into the gene content from the MAGs annotation but that information if not currently publicly available.
