This bacterial family of proteins has no known function. Should be in L Block PS00120. Few Plant proteins (Selaginella moellendorffii) and Plastid group (Trypanosoma) Phospholipase A1 activity was identified as the gene product of plaA of Serratia liquefaciens Serratia sp MK1 (Givskov Molin 1993 Song et al. 1999) Phospholipase A of Yersinia enterocolitica contributes to pathogenesis in a mouse model (Schmiel et al. 1998) Gemella sanguinis 9bacl-a0a2n6sev5 protein identified as Mbeg1 in a functional multigenomic screening of human-associated bacteria for NF-kappaB-inducing bioactive effectors (Estrela et al.) since then family called Mbeg1-like (previously DUF_2974)
