awk空間分割の問題

awkで最初のスペースの後に分割することはできません。

$ grep ">" Supplemental_dataset_07_NbE_CDS.fasta | awk 'BEGIN { FS = "\t" } {print $1}' | head
>NbD053290.1 Partial, glutelin type-B 2-like  (XP_016462855.1)
>NbD053289.2 GDSL esterase/lipase At2g38180-like  (XP_016505556.1)
>NbD053288.1 SUMO-conjugating enzyme SCE1  (XP_019223445.1)
>NbD053287.1 bifunctional epoxide hydrolase 2-like  (XP_016470817.1)
>NbD053286.1 uncharacterized protein LOC109221334 isoform X1  (XP_019241352.1)
>NbD053285.2 uncharacterized protein LOC107817905  (XP_016499316.1)
>NbD053284.3 cell division cycle protein 123 homolog  (XP_019248046.1)
>NbD053283.1 Partial, probable rhamnogalacturonate lyase B  (XP_009789094.1)
>NbD053282.1 aluminum-activated malate transporter 2-like  (XP_009760052.1)
>NbD053281.1 Partial, uncharacterized protein LOC107803999  (XP_016483291.1)

残念ながら、次のコマンドは説明の一部を削除します。

grep ">" Supplemental_dataset_07_NbE_CDS.fasta | awk 'BEGIN { FS = " " } {print $1","$2}' | head

>NbD053290.1,Partial,
>NbD053289.1,GDSL
>NbD053288.1,SUMO-conjugating
>NbD053287.1,bifunctional
>NbD053286.1,uncharacterized
>NbD053285.1,uncharacterized
>NbD053284.1,cell
>NbD053283.1,Partial,
>NbD053282.1,aluminum-activated
>NbD053281.1,Partial,

この出力を生成するために上記のコマンドをどのように変更しますか？

>NbD053290.1,Partial, glutelin type-B 2-like  (XP_016462855.1)
>NbD053289.2,GDSL esterase/lipase At2g38180-like  (XP_016505556.1)

よろしくお願いします。
